174612 - POP Server IP and Round-Robin DNS

Status: RESOLVED DUPLICATE of bug 162871

(MailNews Core :: Networking, defect)

Description

[Jim Garrison]

Based on observation of current (1.1) behavior, Mozilla resolves the
POP server address the first time and caches the IP for subsequent
use.  Consider an ISP with round-robin DNS resolution to multiple
POP servers.  If one of those servers goes down, clients with
that IP cached stop working.

I suggest that Mozilla needs an option to force it to requery
DNS every time it goes to the POP/IMAP server for mail.  This will
be a great boon to all sysadmins fielding unreproducible 
"My mail doesn't work" complaints, especially where their ISP
went from a single POP server to four servers on round-robin DNS
without telling anyone :-)

I can verify dupe, but I think this should be a depends, because mailnews is
going to have to start testing this separately, if this is ever fixed.
