[Dovecot] Minor bugs still in test77
by Chris Wakelin 13 Jul '05

13 Jul '05

Thinking of patches I always apply, I've got a couple (attached) that fix minor bugs and maybe should be applied - or implemented better and then applied ;) - to the main distribution? 1) LIST bugs: LIST "~/mail/" "" and LIST "" "~/mail/" (where "~/mail/" is a namespace prefix) don't reply the same way as UW-IMAP does and in at least the first case, still violates the spec (your fix breaks, as namespace_find() modifies its argument) The second issue breaks Pine 4.x, I think. 2) Angle-addresses If a header address is just "<someone(a)somewhere.org>" rather than "Someone <someone(a)somewhere.org>" or "someone(a)somewhere.org", then the FETCH ... ENVELOPE command responds with "" as the personal name, rather than NIL, which may confuse clients (without being wrong, technically, I think). (In case anyone's interested, I also use patches to: 1) fix the 64bit issue mentioned earlier today 2) introduce extra logging of LIST, SUBSCRIBE and UNSUBSCRIBE (for debugging during our migration from UW-IMAP) 3) rename .subscriptions to .mailboxlist and store folder names in it including the namespace prefix (to emulate UW-IMAP) 4) implement a Reading-specific hashing algorithm for the mail spool location as an extra variable modifier "%H" (e.g. "/export/mail/%Hu/%u/INBOX") 5) remove the need for /dev/urandom, which isn't available on our mail server (though there is a Solaris patch available to create it). 6) add an option to hide "AUTH=PLAIN" in the CAPABILITY string as Pine 4.x complains loudly when this is advertised on a non-SSL connection ) Best Wishes, Chris -- --+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+- Christopher Wakelin, c.d.wakelin(a)reading.ac.uk IT Services Centre, The University of Reading, Tel: +44 (0)118 378 8439 Whiteknights, Reading, RG6 2AF, UK Fax: +44 (0)118 975 3094 --- dovecot-1.0-test77.orig/src/imap/cmd-list.c Sun Apr 17 17:37:05 2005 +++ dovecot-1.0-test77/src/imap/cmd-list.c Wed Jul 13 16:10:27 2005 @@ -372,7 +372,8 @@ concept which probably no other client uses than Pine.

[Dovecot] New to dovecot, little luck - signal 10 death for imap
by Jeroen Scheerder 13 Jul '05

13 Jul '05

Hi, I'm a new prospective dovecot user. I'm planning to migrate a medium-scale mail site (a few thousand users) from UW to something better. I've set up dovecot on a test system. I can connect and authenticate just fine. IMAP clients get to see the right mailboxes. However, whenever a mailbox is selected, the imap subprocess dies. The log shows: Jul 13 14:52:05 localhost dovecot: imap-login: Login: js [127.0.0.1] Jul 13 14:52:07 localhost dovecot: child 8082 (imap) killed with signal 10 When I either telnet to it manually or run the "imap" process in a terminal window, everything seems to work: ---- Snip ---- * PREAUTH [CAPABILITY IMAP4rev1 SORT THREAD=REFERENCES MULTIAPPEND UNSELECT LITERAL+ IDLE CHILDREN NAMESPACE LOGIN-REFERRALS] Logged in as js x select INBOX * FLAGS (\Answered \Flagged \Deleted \Seen \Draft) * OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft \*)] Flags permitted. * 1300 EXISTS * 0 RECENT * OK [UNSEEN 2] First unseen. * OK [UIDVALIDITY 1119092680] UIDs valid * OK [UIDNEXT 1590] Predicted next UID x OK [READ-WRITE] Select completed. x fetch 1 full * 1 FETCH (FLAGS (\Seen) INTERNALDATE "18-Jun-2005 05:00:02 +0200" RFC822.SIZE 1773 ENVELOPE ("Sat, 18 Jun 2005 05:00:01 +0200 (MET DST)" "Waarschuwing: uw inbox overschrijdt 80% van de groottelimiet (18-06-2005)" (("Super-User" NIL "helpdesk" "phil.uu.nl")) (("Super-User" NIL "helpdesk" "phil.uu.nl")) (("Super-User" NIL "helpdesk" "phil.uu.nl")) ((NIL NIL "js" "phil.uu.nl")) NIL NIL NIL "<20050618030001.B5F3952048(a)goedel.admin.phil.uu.nl>") BODY ("text" "plain" ("charset" "us-ascii") NIL NIL "7bit" 1082 25)) x OK Fetch completed. x fetch 1 body[text] * 1 FETCH (BODY[TEXT] {1082} Beste Jeroen Scheerder, [...] Met vriendelijke groet, het systeembeheer. ) x OK Fetch completed. x list * * * LIST (\Noselect \HasChildren) "/" "Archive/" [...] * LIST (\Unmarked) "/" "INBOX" x OK List completed. ---- Snip ---- I'm at a loss here, and no amount of logging or sniffing with tcpdump has revealed anything interesting so far.

I think you need to take your biases and go someplace else. If you don't like MySQL because of some personal bias, then don't use it. Anyone halfway competent can build Dovecot themselves and not rely on some third-party RPM's that have dependencies. This is a discussion list for Dovecot. Please try and stay on topic...

[Dovecot] Headers "missing" in new CVS version
by Todd Burroughs 13 Jul '05

13 Jul '05

We're experiencing an odd problem with dovecot "losing" headers. This started happening with the CVS release as of July 4 and still happens with July 12. It was working properly June 28. It does not happen using pine or thunderbird. It happens using webmail (twig). When you open the inbox, you see subject, etc. When you open a mail, all of the headers are gone. Returning to the inbox, all the headers are missing. It seems to cache this as well. After returning to the older dovecot, all of the headers are missing. Deleting the cache files fixes this and there does not seem to be any mbox corruption. It does not log any errors or crash. Todd Burroughs

[Dovecot] separate SSL certificates for pop3s and imaps
by Michael Weiser 13 Jul '05

13 Jul '05

Hi, I'm migrating a uw-imap installation to dovecot. With uw-imap I had different SSL certificates and keys for ipop3d and imapd. How can I configure dovecot to do the same with its pop3s and imaps services?

[Dovecot] add inotify support to dovecot
by Johannes Berg 13 Jul '05

13 Jul '05

Hi, attached patch against test76 adds inotify support and the --with-notify=... configure option that defaults to the current check for dnotify using no special method if dnotify cannot be compiled, and can be set to none, dnotify and inotify. If it is set to dnotify or inotify, failure to compile a test program results in an error. Also, it adds | file change notification method ..... : <method> to the output at the end of configure. The only thing I don't like about this patch is the fact that I had to add a field notify_context to struct io, but I didn't see a different way to handle this. Also, the patch doesn't support the condition parameter, it simply always asks for all the relevant changes. I don't really see that it is useful for in the context of file system notifications anyway. I modeled this after ioloop-notify-dn.c with my other patch applied to it, if you don't like the other patch you'll want to "revert" that change in the new ioloop-notify-inotify.c file as well. Oh, and obviously I didn't include patches to configure and all the Makefiles, so of course you'll have to run automake. But you already knew that :) I only tested this with maildir. I did add IN_MODIFY so I think it should work with mbox too, but someone should probably verify. Have fun, johannes

[Dovecot] sorting question
by Johannes Berg 13 Jul '05

13 Jul '05

Hi, If I understand the thread sorting algorithm correctly (from draft-ietf-imapext-sort-17.txt and the code), it will sort like this (where I use numbers instead of dates with higher numbers being newer mails) 4 10 3 11 2 12 1 13 etc into all the lower levels. Thunderbird will actually sort this like this: 1 13 2 12 3 11 4 10 where threads are sorted by the newest child in them. Now, I am thinking that evolution simply uses dovecot's THREAD feature and doesn't implement anything itself, so that if I wanted to have that kind of threading, I'd have to implement it in dovecot. Would this be easy? I'm thinking that I should just treat all nodes as if they were dummy nodes in sort_root_nodes, but that only fixes the first level afaict, because later dates are not propagated up. Essentially, I think what the algorithm tb uses does is not use a nodes date as it's sorting criterion, but it's newest child, and apply this rule recursively. Does anyone else think this feature would be useful? I regularly end up almost missing mail because it is sorted at such a low position and I don't see the thread at all.. johannes

[Dovecot] Dovecot runs as ...
by Matt Juszczak 13 Jul '05

13 Jul '05

Hi all, We're using LDAP 100% for everything ... So does that mean that for the following user, I can put another user, like nobody? user = root I guess that user still has to be able to access /var/mail and such, correct?
