I am not the system administrator for qmail or Cyrus and am a newbie to qmail so bear with any incorrect statements. I tried to look up the FAQs for qmail but did not find anything specific to this problem. We have been seeing a strange problem with mail not being delivered to the mailbox. We have qmail (release 1.03) mail transfer agent running on a linux box. Mail is delivered to Cyrus (IMAP v1.5.14) using the following command |preline -f /usr/cyrus/bin/deliver -a sb -e sb We have an application that listens to the mailboxes on the Cyrus server using the javamail API. We have situations where more than one application program may be listening to the same mailbox at the same time. We run into a situation about once in every two days or so where mail does not get delivered to the mailboxes. The qmail logs don't give any error messages. We see that qmail is trying to deliver messages but there is no notification of successfuly delivery. The imap server is fine though because we can still process existing emails. Only new messages encounter this. At this point, our system administrators just give up and reboot both qmail and Cyrus. Once the servers are rebooted, all the messages appear correctly in the mailbox (even the new ones that seemed to be hung somewhere). Has anybody faced this problem before? Any ideas as to what might be going on? Is it possible that multiple clients accessing the same mailbox is somehow causing this problem? Any pointers would be greatly appreciated. Thanks. -- Ashish P. Narvekar email: [EMAIL PROTECTED]
