I have been noticing lately that a lot of messages in our queue have
been frozen because Exim is sending bounce messages to non existant
senders (eg forged senders with correct domains - for example
bogus@???). These bonus senders are obviously spamming - and
are sending to non-existant users on our system.
What I would like to to is reduce the amount of bounce messages by
verifying that the recipient address is valid on our system before
accepting the message. I have read the ACLs section in the manual and I
am uncertain as to which ACL block to use and what ACL.
Anybody on this list can suggest what is suitable.
Thanks
Wm.
