We have an odd email setup. Our primary, internal mailserver is an old Solaris 9 system running postfix, imap and pop. This system is really getting bogged down and we plan to move mail to another system soon. But short term we have started running imap and pop services via xinetd on two SL304 systems to offload the main mail server AMAP. All three servers mount the mail directory from the same filer (NetApp) via NFS.
For most users, changing the imap or pop server in the client just works (as it should). But a handful of users, most running Thunderbird on Linux (a couple running default clients on Mac or XP laptops) have found that when they switch servers, they see an empty inbox, or only a handful of the most recent emails there, no matter how many times they try to sync. If they switch back to the slow, original server, everything shows up again. The desktops are running 4.4 and some version of Thunderbird 1.5 or 2.0. Have any of you seen anything like this? Is it an imap (and pop) problem on EL3, or a protocol bug, or what? I don't see it as a thunderbird issue since we have a handful of Mac and Windows users seeing it on clients that came with their MacOS or XP. Of course, weirder things than that have happened... Thanks, Miles
