Good Day, We have been running Squirrelmail/Qmail/Courier IMAP for about 3 1/2 years now without any issue. We have been increasing our number of Maildirs throughout that time. Just this week we have been intermittently receiving Error: Connection dropped by IMAP server. This sometimes occurs when logging in or even after authenticating. Clicking on the web browser refresh button either once or more gets past the error but it occurs over and over during the session. This is happening on our local network not going through any firewall or slow WAN links. We are running SM 1.4.19 and I have not applied any application or system patches recently to have caused this so am stumped. We have the following plugins installed. Installed Plugins 1. administrator 2. compatibility 3. username 4. compose_extras 5. squirrelspell 6. show_headers 7. addgraphics 8. msg_flags 9. quicksave 10. timeout_user 11. unsafe_image_rules Thank you for any assistance or guidance you can provide.
