Okay, besides tcpdump (which really isn't an option in this case because all of my users are using imap over TLS), what do I have at my disposal? I had the following configured in /etc/syslog.conf: !imapd local6.=info /var/log/maillog I like to keep it at this level to keep the noise down in maillog. I changed the line to "*.* /var/log/maillog", SIGHUP'ed, and sent a test email. The logs that were generated by Cyrus in this new configuration did little more for me than confirm that the logs generated by postfix/lmtp framed the entire conversation between it and lmtpd and that if postfix/lmtp logs "250 2.1.5 Ok," then I can rest assured that the message has been recorded in Cyrus' mail store. I guess there really isn't much else to ask for, but I'd still be interested to know if there is anything else relevant that might be of assistance. > Also, you don't mention any other clients -- what happens with > Thunderbird, for example? I will be deploying a Webmail server (Horde) for this client in the very near future. Based on the responses I've received in this thread thus far, I'm not anticipating any problems. >> This problem trickled in slowly, but have become increasingly worse, to >> the point that many of my users are using Yahoo mail because our mail >> server is "unreliable."

I seem to recall reading about some issue with Outlook throwing a temper tantrum when it can't get its way. I don't remember the exact details, but it seems like the end result of which is that it floods the server with multiple connection attempts (or something similar), which bogs down performance on the server to the point of affecting every user on the network. Can anyone confirm this? -- Anthony Chavez http://anthonychavez.org/ mailto:[EMAIL PROTECTED] jabber:[EMAIL PROTECTED]
