The mailing list for listmasters using Sympa

[Wolfgang Zeikat <address@concealed>]

I forgot:

In postfix' main.cf:
smtpd_recipient_restrictions =
 check_sender_access regexp:/etc/postfix/regexp.sender_access

In /etc/postfix/regexp.sender_access:
/<>/ bounces_allowed

Cheers,

-------- Original Message --------


We have worked around that problem by changing the bounce messages'
"From:" header line in our MTA (postfix) before the mail is passed to
sympa. We apply this only to certain list addresses where the reception
of bounce message is explicitly wanted.

Details:

In postfix' main.cf:

smtpd_restriction_classes =
 bounces_allowed

bounces_allowed =
  check_recipient_access regexp:/etc/postfix/regexp.recipient_rules


In /etc/postfix/regexp.recipient_rules:

# Recipients with special treatment
/^address@concealed$/ FILTER bounceme:[127.0.0.1]

In postfix' master.cf:

bounceme        unix  -       n       n       -       -       pipe
    user=sympa argv=/etc/postfix/change-fromheader.sh ${recipient}

In /etc/postfix/change-fromheader.sh:
#!/bin/bash
RECIPIENT="$1"

perl -pe
's/^(From:.*)(mailer-daemon[@]\S*[a-z]+\b)(.*)/${1}something\@ourdoma.in${3}/i' 

|/opt/products/sympa/5.1.2/bin/queue  $RECIPIENT

logger -p mail.info -t bounceme "Processed message for $RECIPIENT"


Hope this helps,
