I'm currently facing a mail delivery problem. The sending MTA is Exim 4.50. The host has no real IPv6 connectivity, but a working IPv6 stack, and the DNS resolver returns AAAA records.
Mail to domains which are handled by MX hosts which have both an A and AAAA record bounces sporadically with the error message "retry time not reached for any host after a long failure period". The interesting thing is that the bounce itself gets through, after delivery of the original message has failed. "exim -bt" shows that Exim gives indeed priority to the AAAA record. Does this problem sound familiar? I don't have sufficient permissions to check the retry database or the Exim logs, I'm afraid. (The problem may not be related to IPv6 at all, maybe it's just a corrupt retry database.) -- ## List details at http://www.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://www.exim.org/eximwiki/
