From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:0.9.5+) Gecko/20011010 Netscape6/6.1b1 BuildID: 20011208 When sending a mail through a FQDN which maps to multiple IP addresses, only the first one is used even if it fails. One needs to close Mozilla and restart it several times in order to catch the "good" IP. Reproducible: Always Steps to Reproduce: 1. Use an fqdn which maps to several IP for your smtp server with one IP down. 2. Try sending one mail, quiting mozilla, launching mozilla, sending, quiting, ... several times Actual Results: Sooner or later sending fail. when failing a tcpdump shows that the smtp connection is tried on the same IP at every try. Expected Results: Send the message through one of the available IPs. Most probably Mozilla uses only the first IP returned by the resolver. The order of IP adresses is roughly random, so the problem might be difficult to catch. Workaround : for experimented users, entering a known good IP address.
