[Dovecot] How to disable SSL and TLSv1.1?
by Darren Pilgrim 16 Aug '16

16 Aug '16

I'm running Dovecot 2.2.5 and want to make it refuse SSLv2, SSLv3 and TLSv1.0. Clients will opportunistically use TLS 1.1 and 1.2, but now I want require they do so. Is it enough to set ssl_cipher_list = HIGH:!SSLv2:!SSLv3:!TLSv1.0:!aNULL:!MD5 or are there additional settings I need to specify?

[Dovecot] Patch: 2.0 support for URLAUTH, BURL, CATENATE
by Mike Abbott 18 Apr '16

18 Apr '16

Thank you Timo for beginning the port of URLAUTH, BURL, and CATENATE from 1.2 to 2.0. Attached please find two patches that finish the port to 2.0. One patch updates the dovecot-2.0-urlauth branch and is based on the tip of that branch. The other patch adds the full support to dovecot-2.0.beta5. The resulting URLAUTH/BURL/CATENATE code is the same. Please let me know if you have any questions about these patches. Thanks.

[Dovecot] dsync replication errors
by Oli Schacher 09 Sep '15

09 Sep '15

Hi I'm trying to build a cluster of two servers with dsync replication (based on http://wiki2.dovecot.org/Replication) My test setup works fine for very simple tests, I can log in to both servers, copy a message to one of the servers and it successfully apperars in the other account. But, if I try to copy a large amount of messages at once to one of the accounts, my maillogs get flodded with errors(see below) and the mailboxes seem to get out of sync and messages are duplicated over and over again (I originally copied 100 messages and ended up with thousands in both mailboxes until I killed dovecot) I'd appreciate if someone could have a look at my config and tell me what I did wrong. dovecot.conf of both servers, they are identical except for the target ip in mail_replica: dovecot -n # 2.2.beta1 (070ca24e5846+): /etc/dovecot/dovecot.conf # OS: Linux

[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.

[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] failed: Message has been copied too many times
by Angel L. Mateo 19 Feb '14

19 Feb '14

Hello, I'm running dovecot 2.1.16 in a ubuntu 12.04 server, with lazy_expunge, SiS and mdbox format. The problem I'm having is that the index for one the mailboxes of one of my users is growing too much. This is not the first time of this problem. In previous cases, is because a message is duplicated thousand of times (I haven't found any reason for this). In these cases, moving messages to other folder and moving again to this same folder fixes the problem. So I have tried this, and I have moved all messages from this folder to another one. But this time, after this, indexes directory is still using a lot of space. And the folder seems to have more serious problems: amateo_adm@myotis51:~$ sudo doveadm search -u vlo mailbox BORRADOS.INBOX.MNCS doveadm(vlo): Error: Syncing mailbox BORRADOS.INBOX.MNCS failed: Message has been copied too many times (59306 + -1) I have tried to delete the folder, with the same result: amateo_adm@myotis51:~$ sudo doveadm mailbox delete -u vlo BORRADOS.INBOX.MNCS doveadm(vlo): Error: Can't delete mailbox BORRADOS.INBOX.MNCS: Message has been copied too many times (59306 + -1) And to purge user's mailbox, but it didn't fix the problem. PS: If this could help, BORRADOS. is the namespace used by lazy_expunge plugin. -- Angel L.
