[Dovecot] Broken dovecot-uidlist files
by Ulrich Zehl 24 Feb '09

24 Feb '09

I have just upgraded to 1.1.8, hoping to fix these types of errors: Jan 20 10:39:27 laura deliver(xxxxxx(a)example.net): Broken file /srv/storage/mail/store/net/example/xx/xxxxxx/Maildir/dovecot-uidlist line 156: Invalid data: Jan 20 10:41:19 laura dovecot: POP3(yy.yy(a)example.at): Broken file /srv/storage/mail/store/at/example/yy.yy/Maildir/dovecot-uidlist line 2: Invalid data: Unfortunately, they still pop up. Since I suspect these errors to be responsible for customers complaining about downloading mails twice, I'd like to fix them. Our setup has multiple servers sharing the same NFS-mounted directory for maildirs and indexes; we have set mmap_disable = yes dotlock_use_excl = yes fsync_disable = no mail_nfs_index = yes lock_method = fcntl As far as I can tell, for at least one of these errors, there was no concurrent access to the mailbox in question. What can I do to solve this problem, or to analyze it further? Ulrich

This is with respect to an error that I am facing in dovecot. The error is that is seen in logs is "Feb 23 00:04:46 mailblade1 dovecot: IMAP(USERNAME): /indexes/USERNAME/.INBOX/dovecot-uidlist: Duplicate file entry at line 7: 1234776125.M559298P3988.s2o.qlc.co.in,S=13111,W=13470:2, (uid 94277 -> 97805)" This error is seen for multiple users.

[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

[Dovecot] from postfix deliver to dovecot deliver
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-----

[Dovecot] v1.2.beta1 released
by Timo Sirainen 23 Feb '09

23 Feb '09

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..
