114719 - multiple DNS entries not used when sending mails

Status: VERIFIED DUPLICATE of bug 86917

(MailNews Core :: Networking, defect)

Description

User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:0.9.5+) Gecko/20011010

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.
