[Dovecot] Postfix LDA vs the Dovecot LDA + other quetions
by Linux Advocate 24 Feb '09

24 Feb '09

Guys , 1. What is the benefit of using Dovecot' LDA as compared to postfix's LDA? Will there be better performance? And along the same vein, 2. What is the benefit of using Dovecot's SASL as compared to Cyrus SASL? Is there better performance? 3. Quota Management ( Creating, enforcing, notifying ) - is it done thru dovecot or postfix or are both needed? Regards, mgomez

[Dovecot] pkgsrc-ing sieve and managesieve
by Edgar Fuß 24 Feb '09

24 Feb '09

I'm trying to integrate both the new sieve implementation and managesieve into pkgsrc. Managesieve seems to need some dovecot libraries that dovecot doesn't install (lib-storage/libstorage.a, lib-auth/libauth.a, lib-imap/libimap.a, lib-index/libindex.a, lib-mail/libmail.a, lib-charset/libcharset.a, lib-dict/libdict.a and lib-charset/libcharset.a). There seems to be no provision in pkgsrc for the build of a package needing the work directory of the build of another package. Would it make sense for dovecot to install those libraries?

[Dovecot] sieve-test again
by Ian P. Christian 23 Feb '09

23 Feb '09

I'm not sure what it is I'm doing wrong here, perhaps my 'test' mail is not in the format expected by sieve-test. The 'test' file is a file taken directly from a dovecot maildir - so is in the normal format of having headers, a new line, then the body. There is nothing exceptional about this email. Notice how the header below is 'innocent', however it appears that the test is ignoring this header. # grep DSPAM-Res test X-DSPAM-Result: Innocent # cat sievetest require ["regex", "fileinto","envelope","reject","vacation","relational","comparator-i;ascii-numeric"]; if header :contains "X-DSPAM-Result" "Innocent" { fileinto "moo"; stop; } # sieve-test -c ./sievetest ./test Performed actions: (none) Implicit keep: * store message in folder: INBOX Info: final result: success I don't think it's this header, but rather *all* headers, as the following check also appears to fail. if header :contains "To" "o" { fileinto "Spam"; stop; } Am I mis-using the tool? Thanks, Ian

by Johan Hendriks 23 Feb '09

23 Feb '09

Hello all. I use dovecot in combination with postfix, postfixadmin for virtual users. Deliver to the mailbox now is done by postfix Now i want to enable quota's and therefor i need dovecot deliver. Can i just switch to dovecot deliver? Or must i first do some prrperations in the mailboxes. regards -- _______________________ *Johan Hendriks* *Schavemaker Transport* Tel: +31 (0)251 229098 Fax: +31 (0)251 212016 email: j.hendriks(a)schavemaker.com <mailto:j.hendriks@schavemaker.com> web: http://www.schavemaker.com _______________________ /Confidentiality Notice: The information in this document may be confidential.

[Dovecot] lda catchall
by Stéphane Cottin 23 Feb '09

23 Feb '09

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, I'm using dovecot lda in a qmail / vpopmail testing environnement. I would like to replace vpopmail lda with dovecot's one , because of quotas , sieve filers, indexing while delivering ... Everything is working great, except the catchall. If I want to bounce, a first line like "# bounce-no-mailbox" in the .qmail file works, without this line, emails to unknown addresses are deferred and stay in the queue, because they are deliverable for qmail, but not for dovecot lda. How can I set a catchall email address for dovecot lda ? thx Stéphane Cottin -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iEYEARECAAYFAkmixCcACgkQNgQUYqHIqqvttQCfcNBLd9Qo06g5nMcrfZAwVlpv WegAnj7jIA/XFJWmt/2jkg1sxRYKRaI7 =JTTV -----END PGP SIGNATURE-----

http://dovecot.org/releases/1.2/beta/dovecot-1.2.beta1.tar.gz http://dovecot.org/releases/1.2/beta/dovecot-1.2.beta1.tar.gz.sig Largest changes since v1.1 can be found from http://dovecot.org/doc/NEWS-1.2 Changes since alpha5: - Added support for ESORT extension (also SORT .. RETURN (PARTIAL) from CONTEXT=SORT that allows windowing SORT results) - pop3: If client idles for 10 seconds, commit transaction (allowing mbox to become unlocked). - crashfixes to virtual mailboxes - all kinds of bug fixes, error message improvements, etc. - http://dovecot.org/patches/1.2/stats-plugin.c may give some interesting statistics about commands There isn't really much left to do for v1.2.0 except some small fixing to shared mailbox code. And writing documentation for it..

[Dovecot] IMAP ACLs and global ACLs in v1.2
by Timo Sirainen 23 Feb '09

23 Feb '09

I just committed code for IMAP ACL support based on the code from Kolab people. I did quite large changes though. I also changed how global ACLs are handled. Previously local ACLs could override global ACLs, but now that users are able to modify the ACLs I think it should be the other way around. From what I've heard global ACLs are typically added for things like 1) disallowing user from doing something in specific mailboxes such as expunge messages, 2) giving a specific master user access to some mailboxes ONLY, such as voicemail. For 1) case a user really shouldn't be able to grant himself privileges back but still should be able to share the mailbox to others (so the global ACL should have 'a' privilege). For 2) case a user shouldn't be able to remove privileges from the voicemail. So now the user can freely update the local ACLs in whatever way he wants. But in the end if there are any global ACLs, all the local ACLs for those identifiers are ignored. Also local negative identifiers are ignored, so that e.g. global "user=foo lr" can't be disabled by a local "-user=foo lr" ACL. I guess I should update the Wiki ACL page about how exactly the ACLs are applied now that they're well in my memory. :) One thing I'm not really sure about is the "owner" handling. IMAP ACL specifications have no such concept. I think many/most other servers simply add a default ACL for the user name directly. It's a useful concept though, especially with the global ACLs. So currently Dovecot replies: x getacl inbox * ACL "inbox" "owner" lrwstiekxacd x OK Getacl completed. But should it just internally convert "owner" to "username" when replying? But then again if there's a separate rule directly for the "username" it breaks. Do any of the existing ACL-capable IMAP clients want to see the username in the ACL reply or can they handle "owner" just fine? Also what about global ACLs? The current code just lists them twice with local ACLs, which is definitely wrong: x getacl foo * ACL "foo" "xx" w "xx" lr "owner" lrwstiekxacd x OK Getacl completed. Perhaps the global ACLs could have a prefix character? Maybe '#'? Which reminds me, the current dovecot-acl file is mapped to IMAP ACLs like this: dovecot-acl : IMAP ACL - anyone : anyone - authenticated : authenticated - owner : owner - user=name : name - group=name : $name - group-override=name : !$name So all global ACLs would get the # prefix, like #anyone, #name, #!$name. Any thoughts? BTW. Listing shared mailboxes still doesn't work. I guess we'll see tomorrow if I still have energy to get that done.

[Dovecot] dovecot auth
by ben 23 Feb '09

23 Feb '09

Hi, I'm using dovecot with a passdb-file . When I login using : test(a)testdomain.com I notice dovecot strips off the domainname and looks up everything in front of the @ in his passdb-file... So I went on to configure the following in my dovecot.conf : auth_username_format = %u@%d restarted dovecot, but he still strips of the @ and the domainname ... LOG (sorry for f* up format) : dovecot: Feb 21 12:15:08 Info: auth(default): new auth connection: pid=24483 dovecot: Feb 21 12:15:12 Info: auth(default): client in: AUTH 1 PLAIN service=pop3 lip=195.207.136.102 rip=195.207.136.108 lport=110 rport=36132 resp=AGJlbkBpdHV4LmJlAHRlc3QxMjMu dovecot: Feb 21 12:15:12 Info: auth(default): passwd-file(test@testdomain.com@testdomain.com,195.207.136.108): lookup: user=test file=/opt/dovecot/etc/dovecot.passwd dovecot: Feb 21 12:15:12 Info: auth(default): passwd-file(test@testdomain.com@testdomain.com,195.207.136.108): unknown user dovecot: Feb 21 12:15:14 Info: auth(default): client out: FAIL 1 user=test(a)testdomain.com Can someone enlighten me on how to config it so he looks up "test(a)testdomain.com" fully ? thx
