Hi, Our smtp server has some issues when talking to some remote mx's. This results in a timeout and the message not being delivered (this was discussed on this mailinglist but there doesn't seem to be a real solution available now). When we relay the message through another server the remote mx happily accepts the message. I only want to relay messages through the other server when a timeout occurs. I was thinking of using fail2ban for this. I want to watch the maillog with fail2ban and when timeouts appear I want fail2ban to write a line to the transport??? map. How do I redirect messages with a certain destination mx to another mail server (one of our relays)?
Example: mail to i...@goofyandtheregulars.com will be delivered to mx-cluster-b1.one.com or mx-cluster-b2.one.com. But will give a timeout when talking to that machine. So I want to redirect message to mx-cluster-b1.one.com and mx-cluster-b2.one.com to mx2.youngguns.nl. thanks, Martijn
