A NOTE has been added to this issue. ====================================================================== http://www.dbmail.org/mantis/view.php?id=244 ====================================================================== Reported By: postgresql Assigned To: paul ====================================================================== Project: DBMail Issue ID: 244 Category: IMAP daemon Reproducibility: sometimes Severity: major Priority: normal Status: assigned ====================================================================== Date Submitted: 15-Aug-05 08:55 CEST Last Modified: 13-May-06 08:12 CEST ====================================================================== Summary: Server has to be restarted from time to time Description: We are trying to run dbmail on our company-mailserver. The problem is that we have to restart dbmail at least twice a week because dbmail is not able to establish new connections anymore. In addition to that Mac OS X 10.4 (Mail tool) reports quite a lot of connection errors. >From my point of view there are some bugs in the implementation of the IMAP protocol because even Mozilla mail causes problems from time to time.
Currently we feel that there is a large market for something like dbmail but we cannot use that for customers because it doesn't seem reliable yet. ====================================================================== ---------------------------------------------------------------------- paul - 15-Aug-05 09:03 ---------------------------------------------------------------------- Yes, it is known dbmail will stop accepting connections from time to time. But I would very much like to hear more about the OS X connection errors. I havent heard about any of those recently. I would also like to hear more about the mozilla problems since I use mozilla (tb) all the time. Unless you provide specific information we can act on, I'll have to close this report. ---------------------------------------------------------------------- Arabian - 27-Aug-05 15:30 ---------------------------------------------------------------------- I have the same problem happened few days ago in FreeBSD 5.4-STABLE the DB was MySQL 5.0.9 How can I send you useful info if this happned again to the IMAPD? ---------------------------------------------------------------------- postgresql - 27-Aug-05 16:56 ---------------------------------------------------------------------- the problem with mozilla seems to happen in case of large mailboxes. the strange thing is: it CAN happen (not always) that an emails stays "unread" after being read. this happens especially when i jump around between various mailboxes inside one mozilla / tb. i did not find a "rule" for this behaviour yet but it seems to happen more often when dealing with brand new mails. as far as the OS X issue is concerned: in some cases i get the "attention" symbol. again, no rule when this issue happens. i would be happy if i could provide me useful information or even a patch but things seem to be completely random. hans ---------------------------------------------------------------------- paul - 29-Aug-05 22:41 ---------------------------------------------------------------------- I'm pretty sure the osx problem is fixable, but not without a full trace_level=5 log. I need a protocol trace, preferably against a 2.1.2 server which provides better logging of the protocol layer. Or an ethereal log would be even better. As to the problem with mozilla; could be any of several things. But you're probably pushing a limit in dbmail here. Mozilla retrievs a lot of header information from messages when opening a mailbox. This currently still requires reading and parsing *all* unread messages. That is still too slow, but the framework is already in place to speed that up dramatically by using the new header tables. More work-in-progress just like the search speedups. ---------------------------------------------------------------------- aaron - 13-May-06 08:12 ---------------------------------------------------------------------- Have the bug reporters continued to have trouble? There's been a lot of work on DBMail since last year, and Paul's done a ton of heavy lifting on the IMAP code. It's far more robust in recent 2.1's than in earlier 2.1's. I'm going to close this bug soon if there aren't any ongoing problems.
