Hello all, Recently, I was setting up SpamAssassin and procmail on my system (used to run Courier, and was converted using Courier convert scripts). I was setting up a rule in PINE to filter all previously marked SPAM messages into a folder, when I suddenly got disconnected from the IMAP server. I attempted to reconnect, but any attempts to access my INBOX would disconnect me. I looked in /var/log/mail.log on my server, and found this: Mar 26 12:42:17 dashnine dovecot: imap-login: Login: user=<joshua>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured Mar 26 12:42:17 dashnine dovecot: imap(joshua): Trying to allocate 0 bytes Mar 26 12:42:17 dashnine dovecot: child 31035 (imap) killed with signal 6 Looks like Dovecot aborted. I grabbed a tcpdump of the event after turning off SSL, which is available at http://joshuawise.com/pine.imap.tcpdump . My system is, summarized: * A Linux x86 machine: Linux dashnine 2.6.12.3 #2 Sun Aug 7 18:56:14 EDT 2005 i686 GNU/Linux * A Debian machine: testing/unstable * Running Dovecot from Debian: 1.0.beta3 * Converted from Courier using convert scripts * Using Postfix and Procmail * Using Maildirs in home directories (although in this case, lrwxrwxrwx 1 joshua joshua 23 Mar 11 22:08 Maildir -> /media/Maildirs/joshua/) * Using PINE connecting to Dovecot on localhost to access email Let me know if you want more information, or if you want me to try anything in particular. Thanks, joshua
