Re: [exim] How to tell Exim not to issue mailer daemons

I've eventually solved it like that way:

mailerdaemon_filter:
  driver = accept
  domains = ! +local_domains : ! +relay_to_domains
  condition = "${if and{\
                  {eq{$sender_address}{mailer-daemon@???}}\
                  {!eq{$received_protocol}{mailerdaemon-filter-scanned-ok}}\
                       }\
                {1}{0}}"
  transport = mailerdaemon_filter

mailerdaemon_purge:
driver = accept
domains = ! +local_domains : ! +relay_to_domains
condition = ${if eq{$h_X-PurgeMailerDaemon:}{YES} {1}{0}}
transport = mailerdaemon_purge

The mailerdaemon_filter parses the message, looking for specific strings ("host XX.XX.XX.XX \[XX.XX.XX.XX\]: .* Message rejected as spam by Content Filtering" for example). If found, it adds the X-PurgeMailerDaemon SMTP header which triggers the mailerdaemon_purge router.

Subject: [exim] How to tell Exim not to issue mailer daemons

Hello,

My Exim server acts as a virus scanner and an SMTP relay for some domains. When those remote MTA refuse emails - because they are spam for example -. Exim gets a 5xx code and so issues a MD back to the sender.

I'd like to disable mailer-daemon when Exim gets some kind of 5xx codes. Is this possible ?

Christian
