Don’t autorespond to forwarded messages

Posted on 2009-03-04 by Dave Warren (everything-mdaemon.com) — No Comments ↓

It is sometimes desireable to avoid autoresponding to messages that have been forwarded from one local user to another.

This is especially useful if you regularly forward mailboxes to multiple destinations and want to avoid each of those destinations from generating their own autoresponses.

This whitelist allows you to enter both email addresses (which aren’t useful here) as well as headers that will cause an autoresponder to be skipped, in this case we’re adding the X-MDRedirect header, a header MDaemon adds when a message is forwarded.

Go to the Accounts menu
Select “Account Settings”
Find “Auto Responders”
Open the “White List” submenu
Add “X-MDRedirect: 1” to the autoresponder whitelist/exception list

Detecting the use of BCC from the content filter

Posted on 2009-02-26 by Dave Warren (everything-mdaemon.com) — 6 Comments ↓

This is a simple content filter rule that will help you in filtering messages where the current destination was BCC’d rather then being listed in the TO or CC field.

Note that this will trip on most mailing lists — This is correct behaviour, unless the mailing list fills in the recipient’s name in the TO field (and most do not), lists are essentially using BCC.

It only works reliably in the LocalQ, it won’t work in the RemoteQ unless you turn off smartspooling, and it only works for mail received via SMTP, not MultiPOP or DomainPOP.

[Rule001]
RuleName=Detect BCC’d messages
Enable=No
ThisRuleCondition=All
ProcessQueue=LOCAL
Condition01=TO|does not contain|AND|$HEADER:X-Rcpt-To$|
Condition02=CC|does not contain|AND|$HEADER:X-Rcpt-To$|
Action01=add header|”X-BCC”,”True”

To use this rule, copy the above text and paste it into the very top or very bottom of your MDaemonAppcfrules.dat file using Notepad, then open the content filter dialog in MDaemon and enable the rule.

No semaphore files needed, no need to restart MDaemon.

MDaemon’s eventlog codes

MDaemon generates a number of entries in the Windows eventlogs to assist administrators in monitoring for specific important events. Below is a list of the various eventlog codes that MDaemon uses at this time:

503	** ALERT ** %s %s:%d could not be initialized [EvNetwork]
504	** ALERT ** DNS server IP address is blank; please provide a DNS server IP [EvDNS]

515	** ALERT ** Failed to start process %s as user ‘%s’ on ‘%s’; started as default user instead; (FailPoint: %d, Error: %d/%d) [EvProcess]
521	** ALERT ** %s gave false logon/password to POP server; user: %s [EvSecurity]
522	** ALERT ** The ‘[Special] RefuseNULLReturnPath’ option is set to YES in MDaemon.ini; this is an RFC violation [EvRFC]
523	** ALERT ** RFC does not require that HELO or MAIL identification match to the sending server yet MDaemon is configured to refuse mail in these cases (Reverse Lookup properties) [EvRFC]
524	** ALERT ** $AVLONGPRODUCTNAME$ subscription/trial has expired; contact %s or visit http://www.altn.com for renewal instructions [EvSecurity]
525	** ALERT ** WorldClient was expected to be running but wasn’t; restart attempt was %s [EvProcess]

Happy monitoring!
