Hi Racke,We have been experiencing the same issue since upgrade to 0.67.0 (yesterday at 19:00 GMT+2 approx.). Imap server connections don't work properly anymore. In /var/log/syslog, the imap log entries stop after initial connection: Apr 18 06:45:02 server imapd: Connection, ip=[::ffff:X.X.X.X] Before, log entries showed information regarding the login user: Â… imapd: LOGIN, user=Â… When testing imapd via telnet: $ telnet server 143 * OK [CAPABILITY IMAP4rev1 UIDPLUS CHILDREN NAMESPACE THREAD=ORDEREDSUBJECT THREAD=REFERENCES SORT QUOTA IDLE ACL ACL2=UNION STARTTLS] Courier-IMAP ready.

See COPYING for distribution information. 01 LOGIN user password After introducing the LOGIN command, there is no further output and seconds later the connection is lost. So it seems the issue is related to the login process. When using other commands via telnet, the imapd server complains as expected: * OK [CAPABILITY IMAP4rev1 UIDPLUS CHILDREN NAMESPACE THREAD=ORDEREDSUBJECT THREAD=REFERENCES SORT QUOTA IDLE ACL ACL2=UNION STARTTLS] Courier-IMAP ready. Copyright 1998-2011 Double Precision, Inc. See COPYING for distribution information. foo foo NO Error in IMAP command received by server. Curiously, after downgrading all courier packages to 0.66.3-4, and imap, imap-ssl to 4.9.3-4 the problem persists.
