Greetings,
The "Bounce to Email" on the ListMail Configuration page turns into a hidden "Return-path" header in the received email. The "Send From Email" for each list is set as the "From" header and is used for display and replies.
Some auto-reply systems correctly send messages to the "From" address. Others send to the "Return-path", which would be processed as a bounce. This unfortunately cannot be avoided as the most popular methods of bounce handling entail using the "Return-path". There are ways to ignore bounces containing certain strings.
In bounce.cgi, after this line:
if($email){
Add this, for example:
# skip if an auto-reply
if(index(lc $email,'autoreply')>-1){ exit; }
if(index(lc $email,'auto-reply')>-1){ exit; }
if(index(lc $email,'out of office')>-1){ exit; }
if(index(lc $email,'will be away')>-1){ exit; }
I plan on providing an interface for setting such strings in LMP soon.
Regards
