MDAEMON SERVER DEFAULT HELP FOR USER ACCOUNTS
Many functions of MDaemon Server can be accessed remotely through the use
of the email transport system itself. For example, you can gain access
to various aspects of your account and can change or reconfigure it by
sending email messages to the server. You can also subscribe or remove
yourself from mailing lists, have files encoded and mailed to you, and
execute server-based processes by sending carefully formatted mail messages
to the server. Some of these control messages require a valid account on
the server and are password protected. You can gain access to your
accounts by using your password. Messages to the server must be directed
to "MDaemon@mydomain.com". For those commands which require a valid
account on the server, the subject of the message must contain the
account's email address and password separated by a comma character - ex:
"arvel@altn.com, MyPassword". Commands are placed within the message body.
There can only be one command per line, but multiple commands can be
batched in the same message.
Account access and control: - The following commands require a valid
account on the mail server. You must place as the subject of the
mail message your email address and password if you wish to gain
access to any of the commands in the next section. The syntax of
the subject line should be "email address, password" (notice the
comma) ex: Subject: arvel@altn.com, mypassword
For any of the following commands to work for you, your system ad-
ministrator must allow your account to originate server control
messages. If you suspect that your remote access has been removed
or is not functioning properly please consult with your administrator.

Command Special Parms Result
============================================================================
USERS none A listing of all users hosted by
the server will be mailed back to
the originator. Accounts which are set
as hidden will not be listed. Also,
this command is inactive unless enabled
via switch in Misc. Options screen.
LIST [listname] A listing of all mailing lists along with
the names and address of members will be
mailed back to the originator. Lists
must be individually configured to allow
this to occur. Passing an optional list
name will return the members of only that
list. Member names are returned only for
members which are local accounts within
MDaemon.
SUBSCRIBE listname [address] {real name}
The originator is added to the member-
ship of the list specified provided that
list exists and allows remote
subscriptions. If an optional address is
specified after the listname then that
address is added rather than the address
found in the FROM: field of the
subscription message.
ex: SUBSCRIBE mygroup@domain.com
ex: SUBSCRIBE mygroup@domain.com
arvel@altn.com {Arvel Hathcock}
UNSUBSCRIBE listname [address] The originator is removed from the
or specified mailing list provided the list
SIGNOFF exists and contains the originator as a
member. If the optional 'address' is
specified then that address is removed.
ex: UNSUBSCRIBE mygroup@domain.com
ex: UNSUBSCRIBE mygroup@domain.com
me@mydomain.com
SUPPRESS listname address (password)
This command adds 'address' to the lists
suppression file. The list's password
must be provided and the list must already
have a suppression file associated with
it.
ex: SUPPRESS list@mydomain.com
me@mydomain.com (PASS)
UNSUPPRESS listname address (password)
This command removes 'address' from the
lists suppression file. The list's
password must be provided and the list
must already have a suppression file
associated with it.
ex: UNSUPPRESS list@mydomain.com
me@mydomain.com (PASS)
DIGEST listname [address] This command sets 'address' to use digest
mode. If no address is specified then the
address of the originator of the message
will be used.
ex: DIGEST list@mydomain.com
me@mydomain.com
NORMAL listname [address] This command sets 'address' to use normal
non-digest mode. If no address is given
then the originator of the message will be
used.
ex: NORMAL list@mydomain.com
me@mydomain.com
NOMAIL listname [address] This command sets 'address' to nomail mode.
The account will enter a suspended state
and will no longer receive list traffic.
If no address is specified then the orig-
inator of the message will be used.
ex: NOMAIL list@mydomain.com
me@mydomain.com
MAIL listname [address] This command returns 'address' to normal
mode from nomail mode. If no address is
specified then the originator of the message
will be used.
ex: MAIL list@mydomain.com
me@mydomain.com
REALNAME listname [address] {Real Name}
This command sets the real name value for
'address' who is a member of list 'listname'
to the given value. The Real Name parm must

specified in a RESULTS TO directive.
NOTE: The PUBLIC catalog doesn't require
a catalog name or password.
ex: GET utils magic-name (mypassword)
ex: GET magic-name

Command Special Parameters Result
============================================================================
HELP none This file is mailed back to the
originator.
RESULTS TO address Subsequent commands which generate
output will direct that output to
the address specified.
ex: RESULTS TO mailbox@host.org
STATUS none A status report on server operations
and current conditions will be mailed
back to the message originator. Since
the information contained in this status
report is considered private, the sub-
ject of the requested message must con-
tain the user name and password of an
administrator level user account like
this: Arvel, 12wsawe
ex: STATUS
MAIL FORMATS none A listing of all the supported
mailbox formats will be mailed back
to the originator.
Ex: MAIL FORMATS
GET ADDRESS none MDaemon will send a message back to the
originator which will contain the current
machine name and IP address assigned to
MDaemon's computer. This is useful when
you want to find out the IP address
assigned by your ISP when using a dynamic
dialup situation. Since the information
contained in this message is considered
private the subject of the requesting
message must contain the administrator
user and password such as:
Administrator, Password.
ex: GET ADDRESS

后面的一大堆英文应该是help文件。开头的几句话吓了我一跳。后来进去一看，邮件账户和邮件都没有改变，这才放心了。只是不知道MDaemon为什么要发这mail，为什么开始显示邮件数目和磁盘空间是0呢？？
