Hello. we have a problem with our email as you can see:
Your mailserver is probably listed because of bounces. If someone sends a virus to a nonexistant user in your domain, your mailserver will probably bounce the message back to the (forged) sender. If your bounces include the full body of the original message, a bounce will include the original virus. These bounces are just as harmful as the original virus itself. We advice mailserver administrators to configure their mailservers not to include bodies when bouncing.
If you have sendmail, just add
define(`confPRIVACY_FLAGS', `nobodyreturn')dnl
to your sendmail.mc file. If a line like this already exists, just add `nobodyreturn'.
If you have Postfix, configure bounce_size_limit 1024.
If you have Exim, configure bounce_return_body = false.
If you have Exim 3, configure return_size_limit = 1.
Qmail cannot limit the size of bounces by default. You can use this patch. If the link is dead, you could download this local copy.
---------------------
We tried to set the exim.conf "bounce_return_body = false" but it does not help. The body is still included in the bounced mail.
Does someone have advise what we can do?
