Every now and then I have a problem with large email messages in user's inboxes. Most of our users use the pop3 daemon to access their mail. Subsequently, this isn't an issue if they use IMAP. IMAP seems to be able to pull the message down just fine. Anyway, most of the time, large messages can be delivered to the user through pop3 just fine, but sometimes, larger messages will cause microsoft outlook/outlook express to timeout, resulting in the generic, "server timeout" error the outlook clients generate. Also, the users are connecting over a DSL connection to the server which sits on a t-3, so bandwidth shouldn't be an issue.
I've scoured through the logs and I have been unable to find an explanation for this behavior. I've also tried increasing the timeout period in outlook, but that doesn't seem to matter. It just seems to hang on large messages sometimes. Some (most?) might suggest to move away from pop3 and goto IMAP, but that isn't an option for us right now for a few reasons, extenuating reasons actually. Anyway, I was wondering if anyone else has experienced this problem and if so, what steps were taken to remedy this? Or, is this a bug with the pop3d daemon? I'm running Simon Matter's RPM: Cyrus POP3 v2.1.13-Invoca-RPM-2.1.13-3 on redhat 8. Thanks in advance, -joe
