[Dovecot] SASL AUTH
by Tom Allison 02 Jan '05

02 Jan '05

I'm reading through the dovecot wiki pages for virtual hosting with postgresql/postfix/dovecot/debian and it looks pretty nice but I think I'm going to skip the SASL authentication since I'm in a trusted network. I think all I need to do is skip section 5 entirely and bypass all the sasl references in the postfix section. Technically, I don't think any of the SASL has much to do with the dovecot configuration.

[Dovecot] random pool depletion
by Johannes Berg 31 Dec '04

31 Dec '04

I'm facing a problem with dovecot 1.0 test-59; ever since I installed it and use it my random pool is always depleted whenever someone opens an imap connection. This wouldn't be too bad if the machine was used interactively, but since it is not and other services read directly from /dev/random those are sometimes blocked due to dovecot depleting the pool by reading /dev/urandom. Thus my question: is it really necessary to use random numbers from /dev/urandom for temporary filenames? And even if, couldn't it use less? It apparently uses 8 bytes every time. johannes

[Dovecot] delivery agent in 1.0?
by "Branko F. Gračnar" 31 Dec '04

31 Dec '04

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi :) Is there any plan to include delivery agent in 1.x? I would be very happy, if there would be lmtp delivery agent included with dovecot 1.x... This would make creating large mailsystem cluster creation very simple + indexes would be always up2date.

[Dovecot] Authentication difficulties
by Timo Sirainen 30 Dec '04

30 Dec '04

There are constantly pretty basic questions in this list (and in my inbox) about how to get user authentication work correctly. This means that the documentation how it all works is either bad, or people don't find it easily. Any ideas how to improve it? I did this now: - Documentation link in dovecot.org now points directly to Wiki, so people don't go read the outdated documents - Upcoming 1.0-tests and 0.99.13 will contain doc/USE-WIKI-INSTEAD file pointing to Wiki: http://dovecot.org/list/dovecot-cvs/2004-December/003928.html - Updated comments in dovecot-example.conf: http://dovecot.org/list/dovecot-cvs/2004-December/003924.html - Added pointers to Wiki in dovecot-example.conf: http://dovecot.org/list/dovecot-cvs/2004-December/003927.html How good are the Wiki documents about user authentication in general? The content should probably be split somehow to "getting started" vs. "everything there is to know about it" and "system users" vs. "virtual users". I'm not really sure how to best do that though. I think the Wiki in general could be better organized. Wish I knew how.

[Dovecot] Maildir owner importance
by Roi Efrati 29 Dec '04

29 Dec '04

I have set up a directory (/var/local/virtualdir/) as the maildir with a special user/group (virtualmail) and in it I create directories for each domain (example1.tld, example2.tld etc) and sub dir's for each mailbox). Only at the moment, apart from the first one, they are all created as with user root as the owner. How important is to have all the directory tree owned by the same user group (virtualmail:virtualmail) ?

[Dovecot] bug in 99.13-rc2 in ldap md5 patch
by Farkas Levente 29 Dec '04

29 Dec '04

hi, it takes me another hour do debug it again, although i already report it for both joshua and timo. the original patch for openldap's md5 crypt has a small bug. in passdb-ldap.c the schema is already PLAIN-MD5 since that was set in the other part of the original patch in password-scheme.c. do anybody use dovecot with ldap and md5 password? i don't think so:-( this patch would be useful to apply before the final 0.99.13. anyway in the current 1.0 series the PLAIN-MD5 and LDAP-MD5 schema are different. at least plain_md5_verify and plain_md5_generate differ from ldap_md5_verify and ldap_md5_generate. why? -- Levente "Si vis pacem para bellum!" --- dovecot-0.99.13/src/auth/passdb-ldap.c.lfarkas 2004-12-22 17:06:25.000000000 +0100 +++ dovecot-0.99.13/src/auth/passdb-ldap.c 2004-12-22 17:06:56.000000000 +0100 @@ -109,12 +109,11 @@ } /* Special case for OpenLDAP's MD5 type */ - if (strcasecmp(scheme, "MD5") == 0) { + if (strcasecmp(scheme, "PLAIN-MD5") == 0) { buf = buffer_create_static(data_stack_pool, 16); if (base64_decode(password, strlen(password), NULL, buf) == 1 && buffer_get_used_size(buf) == 16) { password = binary_to_hex(buffer_get_data(buf, NULL), 16); - scheme = "PLAIN-MD5"; } }

[Dovecot] Deleting a message through IMAP
by Doug Eubanks 28 Dec '04

28 Dec '04

I have been having a problem with the test releases...I am now using Test 59. When I delete a message using SquirrelMail (IMAP) the message stays in the message list....but you can't open it anymore because it can't be found, if I logout and log back in...the message is gone from the list. I thought it could be a problem with the cache, so I added mail_never_cache_fields = MessagePart Envelope Body only to recieve Dec 24 09:23:34 news dovecot: IMAP(admin): mail_never_cache_fields: Invalid cache field name 'Body', ignoring Any ideas? This problem has plagued me for a while and I always go back to using the and older test like 22 and the problem isn't there... Doug

[Dovecot] Moving existing MD5 passwords to LDAP?
by Ben Beuchler 28 Dec '04

28 Dec '04

I have a dovecot installing working quite well for around 1000 users using passwd-file authentication. I'm moving to LDAP and would sure love to be able to migrate the existing MD5 passwords. I've tried using ldapmodify to set "userPassword" to {CRYPT}$1$H8JE0k5X$y.ptShgYbOgWF.99lX88N1 and {MD5}$1$H8JE0k5X$y.ptShgYbOgWF.99lX88N1 In both cases, ldapmodify exits without errors but I cannot bind using the new password. Any ideas? -Ben -- Ben Beuchler There is no spoon. insyte(a)emt-p.org -- The Matrix
