http://bugs.exim.org/show_bug.cgi?id=815 Summary: Fallback fials if DNS fails Product: Exim Version: 4.69 Platform: Other OS/Version: Windows Status: NEW Severity: bug Priority: medium Component: Routing AssignedTo: [email protected] ReportedBy: [email protected] CC: [email protected] Consider the folowing router: process_and_forward: driver = manualroute domains = +preprocess_domains transport = process_and_forward_smtp route_list = * ${lookup{$domain}dbm{/etc/exim/control/run/preprocess.db}{$value}{}} fallback_hosts = retry.ctyme.com no_more If the receiving server fails the message is forwarded to the fallback_hosts server. However suppose the domain is example.com and the DBM file points to forward to mail.example.com - but the host mail.example.com fails to resolve. In this case the message is NOT forwarded to the fallback server. I think this is a bug and that a DNS failure should cause the fallback condition to execute. This is important to me because I'm using a ram disk for the email queues on my main server for speed. But what I want to do with this server is try to forward one time and if there is any failure to lateral the message off to the retry server that does store the queue on hard disk and will retry for 4 days. What happens on DNS failure is that email gets stuck in the queue and starts filling up ram disk. I do have 8 gigs of ram and it hasn't yet been a problem. But I don't want to store email in ram beyond a single delivery try. -- Configure bugmail: http://bugs.exim.org/userprefs.cgi?tab=email -- ## List details at http://lists.exim.org/mailman/listinfo/exim-dev Exim details at http://www.exim.org/ ##
