Errors on Cross-Protocol Locking nbmand (ZFS Solaris)
by Andrew Watkins 17 May '16

17 May '16

Hello, I get the following errors when I move large e-mails (i.e. about 15MB) into mail files. May 17 13:26:48 mailer3 dovecot: [ID 583609 mail.error] imap(andrew): Error: fdatasync() failed with mbox file /home/andrew/Mail/nbmandON/mbox: Permission denied May 17 13:26:48 mailer3 dovecot: [ID 583609 mail.error] imap(andrew): Error: ftruncate() failed with mbox file /home/andrew/Mail/nbmandON/mbox: Permission denied May 17 13:26:48 mailer3 dovecot: [ID 583609 mail.error] imap(andrew): Error: close() failed with mbox file /home/andrew/Mail/nbmandON/mbox: Permission denied Background I am using Solaris 11 ZFS & SMB for my users home files with Solaris SMB protocol mandatory locking (nbmand=on) If I turn nbmand=off then I do not get any errors, so it is to do with SMB locking. I know this may not be a dovecot error, but any pointers why it is doing this so that I can report it to Oracle. I tried creating a small C program to mimic the same problem but no luck, since I know it would make it easier to get Oracle to fix it. # /usr/local/dovecot/sbin/dovecot --version 2.2.24 (a82c823) Thanks for now, Andrew -- Andrew Watkins * Birkbeck, University of London * Computer Science * * http://notallmicrosoft.blogspot.com * * UKOUG Systems SIG Chair * * UKOUG Tech committee * * tel: 020 7631 6720 *

Hello! At the start dovecot complains all occurrences |mail_plugins settings |in all configs.

Dovecot configuration: Home dir not found
by Divakar BM 17 May '16

17 May '16

Hi, I've my mail solution configured on Server-A with webmail, Dovecot and Postfix. I'm trying to deploy only Dovecot and postfix on Server-B to reduce IMAP/POP3/SMTP load on server-A. Please note server-B does not mailboxes. It should be mapped to mailboxes on server-A. While the LDAP query from Server-B to Server-A is going successfully, the imap service on Server-B is throwing the below error. imap(user(a)example.com): Debug: Home dir not found: /mail/vmail/**/ I guess imap is looking for *home dir* in server-B. How do I tel the imap that home dir is on server-A and not server-B. Please let me know if there exists a configuration parameter for the above.. Thanks Divakar

Sieve extension for testing for mailbox
by Jon Kristensen 16 May '16

16 May '16

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi! Which Pigeonhole Sieve extension should I use to process/test a message depending on whether the message is in a particular mailbox? (Is it the mboxmetadata extension by any chance? If so, I would appreciate if someone could tell me what the reason is for it not being enabled by default.) The reason I want to perform this test is that I have configured my MTA to deliver "outgoing" e-mails to my "Sent" IMAP folder, and these messages arrive unread. I would like to mark them as read using Sieve.

fts-lucene crashes on dovecot-2.2.24
by Dmitry Nezhevenko 16 May '16

16 May '16

Hi, I've tried to upgrade to dovecot 2.2.24. It seems that lucene reindex issue should be fixed. But instead of this dovecot indexer-worker crashes very often for me. I'm attaching backtrace. Please let me know if you need backtrace from binary without optimizations. -- WBR, Dmitry

SSL on doveadm port
by Patrick Domack 15 May '16

15 May '16

I have been attempting to setup ssl on the doveadm port. So far this works fine, as long as the global certificate is used. I wanted to use a different certificate, one that machines the machine name, instead of the generic mail certificate, but I have not been able to figure out how to do this. Attempts to add the certificate in the services section with the ssl = yes option, cause syntax error, and dovecot doesn't start. Creating a protocol doveadm section with it, is ignored, and setting up a local section with it in it, is ignored also.

FTS and autoindex in a cluster?
by Peer Heinlein 15 May '16

15 May '16

In a dovecot replication cluster where both sides have fts_autoindex=yes we have a indexer-worker(user(a)example.com): Indexed 1 messages in INBOX on BOTH sides. a) Is that okay because the duplicated message will be skipped or doesn't harm? b) Or should "autoindex" only be activated on one side?

Dovecot 2.1.7 randomly lost emails
by Paolo Rinaldo 13 May '16

13 May '16

Hi Dovecot 2.1.7 Postfix 2.9.6 Maildir backend, emails filtered by a Postfix frontend (Sqlgrey, Amavis). Lmtp delivering emails using a simple sieve script. Ubuntu 12.04 VMware virtual server. When email are CCed to other recipients on the same domain (the same backend), sometimes they are lost. We hosts approx. 1500 mailboxes, the problem occurs one or two times a day. Recently I changed the frontend, the previous one was delivering one email for each recipient, we had a couple of error per year, we thought it was due to client-side error. The frequency increased with the new frontend, no more “splitting” messages for more than one recipient. The following sample is from a client using a POP3 connection, leaving emails on server. the Postfix mail.log May 11 01:26:55 lmail01 postfix/qmgr[7054]: 96E9CA6628: from=<sender(a)external.com>, size=11822371, nrcpt=2 (queue active) May 11 01:26:55 lmail01 postfix/lmtp[3106]: 96E9CA6628: to=<user-one(a)domain.com>, relay=mail4.robinson.it[private/dovecot-lmtp], delay=0.64, delays=0.45/0/0/0.19, dsn=2.0.0, status=sent (250 2.0.0 <user-one(a)domain.com> 0vNzHyptMlezHgAAk+lh+g Saved) May 11 01:26:55 lmail01 postfix/lmtp[3106]: 96E9CA6628: to=user-two(a)domain.com>, relay=mail4.robinson.it[private/dovecot-lmtp], delay=0.74, delays=0.45/0/0/0.29, dsn=2.0.0, status=sent (250 2.0.0 user-two(a)domain.com> 0vNzHyptMlezHgAAk+lh+g Saved) May 11 01:26:55 lmail01 postfix/qmgr[7054]: 96E9CA6628: removed the dovecot-info.log May 11 01:26:55 lmtp(7859, user-one(a)domain.com) Info: 0vNzHyptMlezHgAAk+lh+g: sieve: msgid=<003A2D931FFF0E48A2314A1ADC87E23E8E4BA1DE(a)t49-ms-exmb02.INTRANET.SAKSROOT.SAKSINC.com>: stored mail into mailbox 'INBOX' May 11 01:26:55 lmtp(7859, user-two(a)domain.com) Info: 0vNzHyptMlezHgAAk+lh+g: sieve: msgid=<003A2D931FFF0E48A2314A1ADC87E23E8E4BA1DE(a)t49-ms-exmb02.INTRANET.SAKSROOT.SAKSINC.com>: stored mail into mailbox 'INBOX' I cannot find the email 0vNzHyptMlezHgAAk+lh+g for user-two(a)domain.com<mailto:user-two@domain.com>, nor I cannot suppose problems on the client, nothing changed on the back-end.

How do I share folders ?
by chaouche yacine 12 May '16

Hello dovecot, First poster here. What I want : give a.chaouche(a)algerian-radio.dz list and read permissions on a.chaouche(a)backup.algerian-radio.dz. Let's just discuss sharing the inbox then I can do the same for subfolders, in any. a.chaouche(a)algerian-radio.dz and a.chaouche(a)backup.algerian-radio.dz are two different users. Details about the domains aren't relevant here I guess.
