Some questions there:
1. I sometimes receive delivery notifications if some list user requested
one. The notifications are not bounced to the sender but to webmaster@... Do
other MTA use the errors_to header for that?
2. Sometimes the system has done deliveries half way down the list and then
the next connection times out. Same with secondary servers for that
recipient. So the second half of the list is delayed 10 mins until this one
delivery times out on two servers. How can I handle this? Can I set smtp
timeout to 1 min for the list and default to 5 min for the rest?
