[Dovecot] POP3 and mail retention
by Roman Gelfand 11 Mar '14

11 Mar '14

Using outlook 2010 as mail client, I have noticed that once an email is moved from inbox, it is deleted from the cur/ directory on the server. Is there a pop3 setting on dovecot that would keep emails, with possible retention period, and recognize that this email has been moved from inbox, etc.. If all of this is doable, would setting outlook to delete the email after 14 days work? delete email from the server when emptying deleted folder? Thanks in advance

[Dovecot] dovecot 2 + vpopmail 5.5.0
by Scott Geiger 11 Mar '14

11 Mar '14

I am working on setting up dovecot 2.2.12 with an installed qmail + vpopmail 5.5.0 base. So far I have not had much luck getting the auth to work with vpopmail. Does dovecot 2.2.12 work with vpopmail 5.5.0? So far when I try to authenticate I always get back User Unknown in the log. Thanks

[Dovecot] Sieve/autosubscribe subfolder
by Moritz Augsburger 08 Mar '14

08 Mar '14

Hi, I just ran across the annoying issue, that with lda_mailbox_autocreate = yes lda_mailbox_autosubscribe = yes set, parent folders of newly created subfolders get subscribed without being existent. Let me give an example: In sieve I use fileinto "foo/bar"; but "foo/" does not exist as folder. So the Mailbox "foo/bar" gets created, but without "foo/" being a Mailbox. Nevertheless gets "foo/" subscribed, so that I have a non-existing mailbox in my subscription list, what confuses thunderbird. So, to solve this problem, I would propose - either the implicit creation of foo/ as mailbox or - not subscribing foo/ Moritz

[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] Planning migration
by Alan Chandler 08 Mar '14

08 Mar '14

I think I have a working dovecot installation, and the time has come to migrate my users. There are only 4 of us, so it can be done manually per user. I looked at this page in the wiki http://wiki2.dovecot.org/Migration/Dsync but I am totally confused. 1st off, it uses doveadm, but with commands parameters that dont match my doveadm's man page. In fact they look more like dsync parameters. Is there an error, or am I totally misunderstanding 2nd - if I assume its a dsync set of parameters, the imapc: at the end is a specification of location2. However, again my man page doesn't give any explanation of this. I am wondering, is this an example of an proxy 3rd - where do the imapc_* parameters go in the configuration I can't find any reference to them in the wiki
