I just discovered a problem with the autocreate patches from http://email.uoa.gr/download/cyrus/cyrus-imapd-2.2.3/ which have been discussed today on this list. Since the maintainers of the patches also read the list I think it's okay to mention this here. When the createonpost feature is set, then a new mailbox is created if a mail is delivered to a non existent mailbox via lmtp. Now I discovered that whenever I send mail with postfix to such a nonexistent mailbox, the box is created on the fly but the mail is not delivered until the next time postfix flushes the queue. I tried to figure out what's going wrong but was unable to find it. An strace of the dying lmtpd process can be found here
