标题: MD 7.1 更新情况
---------------------------- 
MDaemon 7.10 - May 11, 2004 
---------------------------- 
 
SPECIAL CONSIDERATIONS 
---------------------- 
 o Portions of this file (or the entire file) may not yet be localized. 
 o AntiVirus "Urgent update" requests will only be processed by MDaemon if they arrive from an Alt-N Technologies IP address. The first "urgent update" received from any other source will trigger a one time email to the postmaster concerning AV issues. 
 o Three new switches were added to the Pruning tab which allow MDaemon to clear out the content of the various Content Filter quarantine folders at midnight each night - these switches are enabled by default. 
 o The new Statistics log file introduced in MDaemon 7.00 is very powerful but it does need lots of disk and CPU power to maintain. A new switch to toggle the creation and use of this log file was added to the Logging options. This switch is DISABLED by default. If you want to continue to use the Statistics log file you will need to enable the new switch. 
 o The 'UseSafeHash' setting has been removed. MDaemon is now only capable of creating time-safe UIDL hashes. If you have had MDaemon configured to use unsafe UIDL hashes your POP users will have all their mail flagged as new and their mail clients will download it again. This will only happen once and won't happen at all for 99% of MDaemon customers. 
 
MAJOR NEW FEATURES 
------------------ 
 * SPF (SENDER POLICY FRAMEWORK) SUPPORT * 
 MDaemon supports SPF queries as an anti-spoofing measure. You can read about SPF here: <a target=_blank href=http://spf.pobox.com.>http://spf.pobox.com.</a> 
 A new set of controls has been added to the Relay Control dialog box which will allow you to configure how you want your server to use SPF. Also, new logging options for logging SPF queries and a new tab for viewing SPF processing in real time was added. 
 Setting up your own SPF records is beyond the scope of this document but you can get instructions on how to do that at the SPF web site mentioned above. 
 * EASIER SPAM FILTER WHITE LISTING (MDaemon PRO only) * 
 A new switch was added to the Spam Filter White List (auto) tab which enables users configured to use their personal address books as a spam filter white list to optionally forward messages to whitelist@<domain.com> and have MDaemon add the sender of those messages to their personal address book file. The address which is white listed is taken from the FROM header of the emails forwarded to whitelist@<domain.com>. 
 Emails sent to whitelist@<domain.com> must be received via SMTP from a session that was authenticated using SMTP AUTH. Also, MDaemon expects the emails forwarded to the above addresses to be sent as attachments of type message/rfc822. Any other type of message sent to whitelist@<domain .com> will not be processed. 
 You can change the address MDaemon uses by editing the following key in the CFILTER.INI file: 
 [SpamFilter] WhiteListAddress=WhiteList@ 
 Note: the last character must be '@'. 
 * VASTLY REDUCED SPAM FILTER FALSE POSITIVES (MDaemon PRO only) * 
 A new switch was added to the Spam Filter White List (auto) tab which helps reduce Spam Filter false positives by automatically adding to a user's private address book any non-local email address which he/she sends an email to. When enabled, any non-local recipient of a local users email address will be automatically added to his/her XML address book file. When combined with the option to use the users private address book file as his/her personal whitelist the number of Spam Filter false positives can be drastically reduced. 
 This option must be enabled globally via the switch mentioned above and enabled individually for each account via a new switch on the account properties Options tab. 
 This option is disabled for accounts that use auto-responders. 
 * BAYESIAN LEARNING FOR POP USERS * 
 A new switch was added to the Spam Filter Bayesian tab which allows users to forward emails to the spam and ham learning folders. When enabled, MDaemon will honor the SpamLearn@<domain.com> and HamLearn@<domain.com> addresses. Emails sent to these addresses must be received via SMTP from a session that was authenticated using SMTP AUTH. Also, MDaemon expects the emails to be forwarded to the above addresses as attachments of type message/rfc822. Any other type of message sent to these email addresses will not be processed. 
 You can change the addresses MDaemon uses by editing the following key in the CFILTER.INI file: 
 [SpamFilter] SpamLearnAddress=SpamLearn@ HamLearnAddress=HamLearn@ 
 Note: the last character of these values must be '@'. 
 * ADDRESS BOOK GROUPS FOR WORLDCLIENT * 
 It is now possible to create address book groups in WorldClient. 
 Currently, groups are not supported in GroupWare contacts folders, and ComAgent does not support them in its address book sync. 
 * DOMAIN FUNCTIONS ADDED TO API * 
 Some basic domain level functions were added to the API. You can now use API functions to retrieve domain settings, change some settings, and save back to disk. You can also create new domains and delete existing domains. See the MD-API.HTML file for more information. 
 
CHANGES AND ADDITIONAL NEW FEATURES 
----------------------------------- 
 o Support for Classless Inter Domain Routing (CIDR) was added. IP's can now be specified using this notation. 
 o It is sometimes useful to force all MultiPOP users to delete old mail from their servers. If you want MDaemon to always delete old mail for all accounts you can enable a new switch in Misc. Options MultiPOP tab. Be aware that this switch is global and overrides the "Leave a copy of message on POP server" setting for all MultiPOP entries for all accounts. 
 o When an account has a quota restriction and someone tries to send them a message the message could be refused at the RCPT stage or after the DATA command has completed and the message has been received. However, refusing the message at the DATA stage results in the entire message being refused for all RCPT recipients. If you would rather have MDaemon reject over quota messages at the RCPT stage only you can change the following option in MDaemon.ini using notepad: 
 [Special] TestQuotaAfterDATA=No (default Yes) 
 o A new switch called "Create secure Received headers" was added to the Misc. Options Headers tab. When this switch is set MDaemon will mask out IP address, PTR lookup results, and local machine names from its Received header stamps when the IP is local or when the message comes in on an AUTH'ed session (this will protect your remote users). This switch is enabled by default. 
 o By default, MDaemon's automatically generated system messages will go through the content filter, spam filter, and anti-virus processing (this is a change from MD 7.0x which did not put these message through this process). If you would like to change this you can set the following key in the MDaemon.ini file using Notepad: 
 [Special] SystemMsgsUseCF=No (default Yes) 
 Note: some automatically generated system messages MUST go through the CF/AV/AF engine because they could potentially contain messages with viruses. 
 o MDaemon's domain format checker was modified to recognize domains which have no '.' character and also domains with the '..' character sequence. In both cases the domain format is invalid. If you would like to omit this format check set the following switch in the MDaemon.ini with Notepad: 
 [Special] OmitPrimaryDomainFormatCheck=Yes (default No) 
 o In the past MDaemon always toggled the CF/AV/AS engine (CFEngine.exe) on and off at midnight. This could be causing some problems so we have disabled this behavior by default. To re-enabled it edit the following key in the CFilter.ini file using Notepad: 
 [ContentFilter] ToggleAtMidnight=Yes (default No) 
 o If you would like to have the automatic extraction algorithm to extract 7bit or 8bit attachments you can set the following keys:

作者: efeng 时间: 2004-5-22 11:21
标题: Re:MD 7.1 更新情况
[Special] Extract7bit=Yes (default No) Extract8bit=Yes (default No) 
 o List messages which are processed by the content filter prior to "crack- ing" can not go through the SYSTEM level rules of the content filter. This creates dozens of potential bugs. This means that the new 7.0x archival features DO NOT work on list messages when the "Apply content and spam filters to list mail before cracking individual copies" option is enabled in Misc. Options. When this switch is enabled mailing list messages ARE NOT ARCHIVED. You will need to devise your own content filter rules to archive list mail at the present time. 
 o The "freeze queue" toolbar buttons were removed from the toolbar when in easy (simple) mode and they were moved to the right to separate them from the "process queue" buttons in advanced mode. 
 o CFILTER.INI was added to the WebAdmin FileList-xx.dat control files. 
 o In the IMAP folder permissions (ACL) editor, the "Set Sub" button will apply the current permissions to all subfolders of the folder being edited. 
 o Some slight internal changes were made to logging and GUI updating to speed things up slightly. 
 o MDConfig was discontinued in 7.00 and it was documented but somehow the documentation about this was deleted. We are focusing our remote administration resources into WebAdmin, Remote Desktop, and Terminal Services support. 
 o The Content Filter, AntiVirus, and AntiSpam GUI and logs will no longer be updated when the features are disabled. Also, the AntiSpam logs will no longer be updated when processing is skipped for any reason (for example, when messages are from local users). This was wasting CPU and disk space. 
 o Messages larger than 200k will not be processed by the Spam Filter during the SMTP transaction. We previously had a 2 meg size limitation here but we've discovered that our code in combination with SpamAssassin causes slow performance and even lockups when processing large messages during the SMTP session. Full Spam Filter processing of all messages up to 2 megs will take place as normal during queue processing. 
 o MDaemon was checking for a spam filter update control file once every few seconds. This creates unneeded disk I/O. The check was moved to once per minute. 
 o The option to honor the APOP/CRAM-MD5 authentication methods (on the Servers page of Misc Options) now also applies to the SMTP server. 
 o An option to include [%d:%d] unique ID strings to session logs was added to the log settings GUI. 
 o Mailing lists are no longer allowed to directly send mail to the MDaemon system account. Attempting to do so will result in a 55x SMTP error. o At midnight MDaemon creates and runs Cleanup.bat. If you would like to run your own midnight batch file you can create a file called MyCleanup. bat and put it in the APP folder. MDaemon will run this instead of Cleanup.bat. Make sure that your MyCleanup.bat file contains calls to AccountPrune.exe (look at Cleanup.bat). 
 o The Standard theme 'Normal' style sheets were updated. 
 o MDStats will prompt if you want to open a log file in Notepad if it doesn't find any POP, IMAP, or SMTP sessions in it. 
 o We changed the write method that the SMTP server uses to store the .CTL files and reduced the number of times SMTP sessions update the CPS rate. This should improve performance slightly. 
 o The active session log window will not be updated unless it is the view currently active. This saves CPU and makes MDaemon faster. When switching to the session window from other windows the initial data on the screen will be out of date or N/A. If you would prefer to keep this tab current even when it is not in view you can set the following switch in the MDaemon.ini file using notepad: 
 [Special] AlwaysUpdateSessionWnd=Yes (default No) 
 o MDaemon's INI caching system now doesn't access disk every time a value not in the INI is requested. 
 o The Composite log file will now rotate just as other log files do. 
 o Public folders will be enabled when using the archive to public folders feature. 
 o An option to reset the system tray icon was added to the Windows menu just in case the tray icon is missing for some reason. 
 o If you are using MYLEARN.BAT you should check it and remove all the lines which reference RESETBAYES.SEM. A bug could have placed multiple copies of that line in your file. Also, the "Apply Bayesian knowledge to heuristic message scoring" switch MUST be enabled for learning to take place. This is handled automatically with LEARN.BAT but, if you want to use MYLEARN.BAT and still leave this switch disabled you will need to place one line like this at the bottom of your MYLEARN.BAT file: 
 dir > C:\MDaemon\App\ResetBayes.sem 
 o A new switch was added to the Mail Scheduler GUI which allows you to have Gateway messages delivered immediately when other remote mail and the Gateway itself is configured to do so. 
 o When MDaemon is configured to reject messages during the SMTP session if they are likely to be spam, the score received by the message will be included in the SMTPI record of the statistics log file. 
 o The account pruner will ignore non-mail GroupWare folders when deleting old mail. 
 o The X-Spam-Processed header will no longer be added when using MDaemon Standard. 
 o When messages are refused by the Spam Blocker the spam refused counter will be incremented. 
 o Gateway LDAP verification lookups will check 'SMTP:<email>' also. This allows LDAP queries to Active Directory/Exchange installations. 
 o The user is notified on WorldClient's login page when a draft message is saved because they tried to send a message after their session had timed out. 
 o The "All Contacts" option in WorldClient's address book now also lists contacts from all GroupWare contacts folders 
 o A WorldClient option has been added to have message list auto-refreshes reset the session's inactivity timer. If you do not want your users timed-out while they leave their browsers open to the message list page, edit \MDaemon\WorldClient\Domains.ini and set: 
 [Default:Settings] HonorNoKeepAlive=No (default is Yes) 
 o Default font and font size for HTML compose added to Compose options. 
 o Added 'Forward as Attachment' capability to WorldClient. 
 o By default, ComAgent's icon blinks when an IM buddy comes online. If you would like to change this you can set the following key in the ComAgent.ini(client-side) file using Notepad: 
 [Events] BlinkOnIMBuddyOnline=No (default Yes) 
 o A new switch was added to the Pruning tab which allows MDaemon to delete all messages more than XX days old from all public folders during the midnight cleanup event. 
 o If a mail folder has the following switch in its HIWATER.MRK file the folder and all sub-folders will be exempt from the old mail pruning process: 
 [Settings] SkipAutoPrune=Yes (default No)
