[Dovecot] imapc - different settings for different namespaces
by Timo Sirainen 20 Mar '15

20 Mar '15

Originally I was planning on allowing all kinds of mail settings inside namespace {}, including imapc_* settings. But that's a bit difficult to implement (although I think it will happen some day). So for now I was thinking: imapc foo { host = imap.foo.com master_user = foomaster password = foopass } imapc bar { host = imap.bar.com ... } namespace { prefix = foo/ location = imapc:foo } namespace { prefix = bar/ location = imapc:bar } So basically if the path after imapc isn't absolute (/path or ~/path), then treat the path as the imapc section name and use its settings. Anyone have any improvement suggestions? I was planning on adding this to v2.2.3. I'm not sure if the section names should be "imapc" or something else (e.g. imap_remote {}).

[Dovecot] Sieve vacation not working
by Phill Edwards 24 Feb '15

24 Feb '15

I've been trying all night to get vacation working in my .dovecot.sieve file. The way our email works is we have one account on dovecot which serves my mail and my wife's and we use procmail and sieve to put the emails in different folders depending on who it's for. I'm trying to set up a vacation reply on my wife's email address (aaaaaaaa@optus* below) so people can update to her new address. Here's my file with the email addresses masked: require ["fileinto", "vacation"]; if address :is "to" "xxxxxxxxxxxxxxx(a)ozemail.com.au" { fileinto "Phill_OzEmail_Folder"; stop; } elsif address :is "to" "yyyyyyyyyyyyyyyyy(a)optusnet.com.au" { fileinto "Phill_Optus_Folder"; stop; } elsif address :matches "to" "aaaaaaaa@optus*" { vacation "Please update my email address to bbbbbbbbb(a)exemail.com.au"; fileinto "Sarah_Optus_Folder"; stop; } else { keep; stop; } The problem I'm having is that no auto-replies are sent. I removed .dovecot.lda-dupes and that didn't help; so then I touched it and now it's a 0 byte file and that didn't help. There is no dovecot.sieve.err file and I can't see anything in /var/log/dovecot.log which gives any message about why this wouldn't work. The emails to aaaaaaa@optus* get filed into the right folder so I know the matching is working. I've also tried a reject recipe and that worked fine, so I know that it can send an email if it chooses to. So it's a complete black box mystery as to why it just won't send a reply. Regards, Phill

[Dovecot] Disk Encryption
by Simon Brereton 17 Oct '14

17 Oct '14

Hi As I understand it email headers need to be unencrypted (otherwise DKIM doesn't work). From the MUA to either Postfix, or Dovecot the connection is (or can/should be) secured with TLS/SSL. What I would like to know is if it is possible to encrypt the mailstore? Postfix is using Dovecot for delivery so it's only Dovecot that would need to encrypt/decrypt the mailstore. Is this possible? Is there a terrible reason to do it even if it is possible? I realise that from MTA to MTA there's no guarantee of encryption (and in fact it's very unlikely unless keys have been exchanged), but my primary goal is supplement the physical security of the mail store of mails we already have or have sent. Mostly just idle curiosity as to what has been done, or what could be done. What is worth doing is a separate thread entirely. Thanks. Simon

[Dovecot] Issues with VANISHED CHANGEDSINCE
by Michael J Rubinsky 09 Jun '14

09 Jun '14

I've been seeing the following wonky behavior with Dovecot. Currently this is with Dovecot 2.0.19, but I was also seeing it in earlier versions as well, including versions from the 1.x series. Some background, this is from Horde's ActiveSync library, when it is trying to determine what UIDs have recently been expunged. I can guarantee that when this command was sent, there was only one or two emails that were removed since the provided MODSEQ value. C: 8 UID FETCH 1:* UID (VANISHED CHANGEDSINCE 587742) S: * VANISHED (EARLIER) 1:119944,119947:123482,123484:128043,128045:130388,130390:130456,130458:132127,132129:135832,135834:136201,136203:136301,136303:136316,136318:138502,138504:140099,140101:141908,141910:142607,142609:142744,142746:142865,142867:143160,143164:143173,143176:143179,143181:143187,143189:143190,143192:143195,143197:143270,143272:143273,143275:143280,143282:143302,143305:143307,143309:143318,143320:143333,143335:143337,143339:143341,143343:143375,143377:143400,143402:143551,143553:143637,143640:143706,143708:144069,144071:144178,144180:144307,144309:144316,144318:144329,144331:144931,144933:144983,144985:145000,145002:145069,145071:145072,145074:145132,145136:145178,145180:145191,145193 Also, to verify it wasn't something screwy with my server, Michael Slusarz provided me with this from his server: <quote> There's definitely something wonky going on in the code. There's a certain tipping point of modseqs where the values become incorrect. For a mailbox with HIGHESTMODSEQ of 54004, I see this: a uid fetch 1:* UID (VANISHED CHANGEDSINCE 53881) * VANISHED (EARLIER) 1:37308,37310:40788,40791:41032,41034:41083 a OK Fetch completed. b uid fetch 1:* UID (VANISHED CHANGEDSINCE 53882) * VANISHED (EARLIER) 41029:41030,41047:41083 b OK Fetch completed. </quote> Thanks for any guidance. -- mike The Horde Project (www.horde.org) mrubinsk(a)horde.org

[Dovecot] Mbox corruption - Inbox beginning with 'FFrom' or 'FrFrom'
by Dimos Alevizos 08 Mar '14

08 Mar '14

Hello, we're having some problems with our dovecot setup. I've seen similar problems in the mailing list some years ago but alas wasn't able to find a solution. Our setup is as follows : An MX farm (postfix) sends mails via LMTP to a director farm (dovecot 2.1.12) which proxies pop3/imap/lmtp traffic to a dovecot farm (dovecot 2.1.16). All mailboxes and indexes are on NFS and all servers are Centos. The problem is that at times we see mailboxes (all of them are in mbox format) beginning with FFrom or FrFrom and of course dovecot says it's not a valid mbox file. If we manually remove the offending extra characters from the beginning of the file everything is working again, but often the same user will show the problem again tomorrow. However it's very rare and so far we haven't been able to reproduce the problem. After activating the mail_log plugin hoping it'll help us locate the problem we run across this case : The user (let's call him user(a)domain.gr) logs in via pop3 and deletes some mails but one of them fails: Jun 19 11:09:18 pop01 dovecot: pop3-login: Login: user=<user(a)domain.gr>, method=PLAIN, rip=83.235.173.26, lip=83.235.66.40, mpid=1389, secured, session=<Ao+rWH3fHgBT660a> Jun 19 11:09:18 director5 dovecot: pop3-login: proxy(user(a)domain.gr): started proxying to 83.235.66.40:110: user=<user(a)domain.gr>, method=PLAIN, rip=83.235.173.26, lip=83.235.66.65, session=<Ao+rWH3fHgBT660a> Jun 19 11:09:24 pop01 dovecot: pop3(user(a)domain.gr): expunge: box=INBOX, uid=20670, msgid=<9f5b1a20a9428ed31a9e7e42ce4411f08d0.20130612070424(a)mail84.us2.rsgsv.net>, size=36526 Jun 19 11:09:24 pop01 dovecot: pop3(user(a)domain.gr): expunge: box=INBOX, uid=20671, msgid=<b27d72dc5a47a3235a232494c6fe8aa0(a)newsletter.stockout.gr>, size=4637 Jun 19 11:09:24 pop01 dovecot: pop3(user(a)domain.gr): expunge: box=INBOX, uid=20672, msgid=<1113670779560.1111910791405.1470.2.32032003(a)scheduler.constantcontact.com>, size=38655 Jun 19 11:09:24 pop01 dovecot: pop3(user(a)domain.gr): expunge: box=INBOX, uid=20673, msgid=<83600a274c1407c5aa4c263e2592cb54(a)debop.gr>, size=1181688 Jun 19 11:09:24 pop01 dovecot: pop3(user(a)domain.gr): expunge: box=INBOX, uid=20674, msgid=<F2A59BE7-007A-4567-9BA5-803446C3D7F8(a)bernier-eliades.gr>, size=61116 Jun 19 11:09:26 pop01 dovecot: pop3(user(a)domain.gr): Error: Next message unexpectedly corrupted in mbox file /var/mail/K/Y/V/domain_gr_user_007 at 1 Jun 19 11:09:26 pop01 dovecot: pop3(user(a)domain.gr): Error: Cached message offset 1 is invalid for mbox file /var/mail/K/Y/V/domain_gr_user_007 Jun 19 11:09:27 pop01 dovecot: pop3(user(a)domain.gr): Disconnected: Logged out top=0/0, retr=2/1502843, del=122/359, size=137448432 Jun 19 11:09:27 pop01 dovecot: pop3(user(a)domain.gr): Warning: Our dotlock file /var/mail/K/Y/V/domain_gr_user_007.lock was deleted (locked 9 secs ago, touched 9 secs ago) Jun 19 11:09:27 pop01 dovecot: pop3(user(a)domain.gr): Error: file_dotlock_delete() failed with mbox file /var/mail/K/Y/V/domain_gr_user_007: No such file or directory Jun 19 11:09:27 director5 dovecot: pop3-login: proxy(user(a)domain.gr): disconnecting 83.235.173.26 (Disconnected by server): user=<user(a)domain.gr>, method=PLAIN, rip=83.235.173.26, lip=83.235.66.65, session=<Ao+rWH3fHgBT660a> However he's still able to log in again : Jun 19 11:11:36 pop01 dovecot: pop3-login: Login: user=<user(a)domain.gr>, method=PLAIN, rip=85.74.231.10, lip=83.235.66.40, mpid=10094, secured, session=<QDLrYH3f7ABVSucK> Jun 19 11:11:36 director3 dovecot: pop3-login: proxy(user(a)domain.gr): started proxying to 83.235.66.40:110: user=<user(a)domain.gr>, method=PLAIN, rip=85.74.231.10, lip=83.235.66.63, session=<QDLrYH3f7ABVSucK> Jun 19 11:11:51 pop01 dovecot: pop3(user(a)domain.gr): Disconnected: Logged out top=0/0, retr=0/0, del=0/237, size=75036938 Jun 19 11:11:51 director3 dovecot: pop3-login: proxy(user(a)domain.gr): disconnecting 85.74.231.10 (Disconnected by server): user=<user(a)domain.gr>, method=PLAIN, rip=85.74.231.10, lip=83.235.66.63, session=<QDLrYH3f7ABVSucK> A few minutes later he receives another mail which is delivered with no problem : Jun 19 11:30:39 corvus amavis[546]: (00546-22) Passed CLEAN, [91.190.168.40] [91.190.168.40] <tk-14439(a)free.splio.com> -> <user(a)domain.gr>, Message-ID: <58175-bWFyaW5hQGJlcm5pZXItZWxpYWR lcy5ncg==(a)free.splio.com>, mail_id: J1P-0WpmQksJ, Hits: 1.412, size: 9025, queued_as: 02BA4AE00414, Tests: [DKIM_VALID=-0.1,DKIM_VERIFIED=-0.1,FREEMAIL_FROM=0.001,HTML_IMAGE_RATIO_04=0.61,INVALID_MSGID=1,URIBL_BLOCKED=0.001], autolearn=disabled, 1533 ms Jun 19 11:30:39 corvus smtp/smtpd[1283]: proxy-accept: END-OF-MESSAGE: 250 2.0.0 from MTA(smtp:[127.0.0.1]:10025): 250 2.0.0 Ok: queued as 02BA4AE00414;

[Dovecot] Dovecot service not responding after about a week of uptime
by Matthieu 15 Jan '14

15 Jan '14

Hello, I am running a dovecot 2.1.13 server and lately it stops responding after about a week of uptime. Simply restarting the dovecot service solves the issue. I tried to look a bit in my maillog file but did not find anything obvious. During the time when the server is not responding I can still see imap-login entries from the connection attempt by my email client. Any help about how to diagnose the problem would be appreciated. Thanks, Matthieu

[Dovecot] RFE: IMAP LIST Extension for Special-Use Mailboxes
by Patrick Ben Koetter 03 Jan '14

03 Jan '14

Timo, would you consider adding support for "IMAP LIST Extension for Special-Use Mailboxes" <http://www.rfc-editor.org/rfc/rfc6154.txt> any time near in the future? I would really love to get rid of all those folders created by all those different mail clients just because they can't agree to use the same folder for special purpose. Obviously clients need to support it too. Having Dovecot support it certainly would make them adopt the standard sooner. p@rick -- state of mind Digitale Kommunikation http://www.state-of-mind.de Franziskanerstraße 15 Telefon +49 89 3090 4664 81669 München Telefax +49 89 3090 4666 Amtsgericht München Partnerschaftsregister PR 563

[Dovecot] Dovecot connection problem - Too many invalid commands (no auth attempts) - v2.0.19
by Thomas Standaert 12 Dec '13

12 Dec '13

Hello. This might be a silly problem, but I'm a bit a newbie at this, and the internet didn't give me a solution to this yet. I installed a mail server with postfix, dovecot, postfixadmin and a mysql DB for authentification, using this tutorial : <http://www.exratione.com/2012/05/a-mailserver-on-ubuntu-1204-postfix-doveco t-mysql/> http://www.exratione.com/2012/05/a-mailserver-on-ubuntu-1204-postfix-dovecot -mysql/. Except step 4. The complete tutorial worked on a virtual machine, but doesn't work here on a vps from ovh.net. Connecting via telnet localhost 143 works, I can connect. When I try to connect via thunderbird, the domain name is picked up, but gives me a bad login/password combination. Mail.log, mail.err and error don't show anything. Via MS Outlook, I seem to get stuck on the connection page, and I get the following errors in mail.log: dovecot: imap-login: Disconnected: Too many invalid commands (no auth attempts): rip=x, lip=y dovecot: pop3-login: Disconnected (no auth attempts): rip=x, lip=y dovecot: imap-login: Disconnected (no auth attempts): rip=x, lip=y, TLS: Disconnected dovecot: pop3-login: Disconnected (no auth attempts): rip=x, lip=y, TLS: Disconnected dovecot: pop3-login: Aborted login (no auth attempts): rip=x, lip=y dovecot: imap-login: Disconnected (no auth attempts): rip=x, lip=y, TLS: Disconnected dovecot: imap-login: Disconnected (no auth attempts rip=x, lip=y dovecot: imap-login: Disconnected (no auth attempts): rip=x, lip=y, TLS handshaking: Disconnected dovecot: pop3-login: Disconnected (no auth attempts): rip=x, lip=y, TLS handshaking: Disconnected And after a while asks to try to connect via plain method.

[Dovecot] When imapc can't connect to remote IMAP prevents user login (and blocks LDA)
by Marcin Mirosław 28 Oct '13

Hi! I'm using dovecot 2.1.12-r1. When remote imap server rejects connections then I can't login into account and MTA can't deliver emails to maildir also. I'm attaching snippets of logs: 2012-12-15T18:05:43.072594+01:00 meteor dovecot: imap-login: Login: user=<marcin(a)mejor.pl>, method=PLAIN, rip=2001:470:1f0b:1ab3:50af:bef4:6918:78ad, lip=2001:470:1f15:1b61::2, mpid=32533, TLS, session=<T0GGKOfQCQAgAQRwHwsas1CvvvRpGHit> 2012-12-15T18:05:43.442598+01:00 meteor dovecot: imap(marcin(a)mejor.pl) <T0GGKOfQCQAgAQRwHwsas1CvvvRpGHit>: Error: imapc(imap.wp.pl:143): Server disconnected: Connection reset by peer 2012-12-15T18:05:43.442598+01:00 meteor dovecot: imap(marcin(a)mejor.pl) <T0GGKOfQCQAgAQRwHwsas1CvvvRpGHit>: Error: imapc(imap.wp.pl:143): Authentication failed: Disconnected from server 2012-12-15T18:05:43.442598+01:00 meteor dovecot: imap(marcin(a)mejor.pl) <T0GGKOfQCQAgAQRwHwsas1CvvvRpGHit>: Error: imapc: Command failed: Disconnected from server 2012-12-15T18:05:43.442598+01:00 meteor dovecot: imap(marcin(a)mejor.pl) <T0GGKOfQCQAgAQRwHwsas1CvvvRpGHit>: Error: user marcin(a)mejor.pl: Initialization failed: Namespace 'xxx-wp-pl.': imapc: LIST failed: Internal error occurred.
