Starting at 05:32 this morning, one user on my dovecot server is receiving hundreds of copies of old email. This is a short excerpt from my dovecot.log showing the problem: > dovecot: Nov 03 05:27:02 Info: pop3-login: Login: > user=<howard(a)obfusca.ted>, method=PLAIN, rip=::ffff:81.44.31.210, > lip=::ffff:zz.zz.zz.zz, TLS > dovecot: Nov 03 05:27:02 Info: POP3(howard(a)obfusca.ted): Disconnected: > Logged out top=0/0, retr=0/0, del=0/0, size=0 > dovecot: Nov 03 05:32:01 Error: POP3(joyce(a)obfusca.ted): mbox sync: > Expunged message reappeared in mailbox > /var/mail/vhosts/obfusca.ted/joyce (UID 1443 < 1446, seq=2, idx_msgs=0) > dovecot: Nov 03 05:32:01 Info: pop3-login: Login: > user=<joyce(a)obfusca.ted>, method=PLAIN, rip=::ffff:67.9.149.201, > lip=::ffff:zz.zz.zz.zz, TLS > dovecot: Nov 03 05:32:02 Info: pop3-login: Login: > user=<howard(a)obfusca.ted>, method=PLAIN, rip=::ffff:81.44.31.210, > lip=::ffff:zz.zz.zz.zz, TLS > dovecot: Nov 03 05:32:03 Info: POP3(joyce(a)obfusca.ted): Disconnected: > Logged out top=0/0, retr=3/163473, del=3/3, size=163419 > dovecot: Nov 03 05:32:03 Error: POP3(joyce(a)obfusca.ted): mbox sync: > Expunged message reappeared in mailbox > /var/mail/vhosts/obfusca.ted/joyce (UID 1443 < 1449, seq=2, idx_msgs=0) > dovecot: Nov 03 05:32:03 Info: POP3(howard(a)obfusca.ted): Disconnected: > Logged out top=0/0, retr=0/0, del=0/0, size=0 > dovecot: Nov 03 05:37:02 Info: pop3-login: Login: > user=<howard(a)obfusca.ted>, method=PLAIN, rip=::ffff:81.44.31.210, > lip=::ffff:zz.zz.zz.zz, TLS > dovecot: Nov 03 05:37:03 Info: POP3(howard(a)obfusca.ted): Disconnected: > Logged out top=0/0, retr=0/0, del=0/3, size=0 > dovecot: Nov 03 05:42:01 Info: pop3-login: Login: > user=<joyce(a)obfusca.ted>, method=PLAIN, rip=::ffff:67.9.149.201, > lip=::ffff:zz.zz.zz.zz, TLS > dovecot: Nov 03 05:42:02 Info: pop3-login: Login: > user=<howard(a)obfusca.ted>, method=PLAIN, rip=::ffff:81.44.31.210, > lip=::ffff:zz.zz.zz.zz, TLS > dovecot: Nov 03 05:42:02 Info: POP3(howard(a)obfusca.ted): Disconnected: > Logged out top=0/0, retr=0/0, del=0/0, size=0 > dovecot: Nov 03 05:42:03 Info: POP3(joyce(a)obfusca.ted): Disconnected: > Logged out top=0/0, retr=3/163461, del=3/3, size=0 > dovecot: Nov 03 05:47:02 Info: pop3-login: Login: > user=<howard(a)obfusca.ted>, method=PLAIN, rip=::ffff:81.44.31.210, > lip=::ffff:zz.zz.zz.zz, TLS > dovecot: Nov 03 05:47:02 Info: POP3(howard(a)obfusca.ted): Disconnected: > Logged out top=0/0, retr=0/0, del=0/0, size=0 > dovecot: Nov 03 05:52:01 Error: POP3(joyce(a)obfusca.ted): mbox sync: > Expunged message reappeared in mailbox > /var/mail/vhosts/obfusca.ted/joyce (UID 1449 < 1452, seq=2, idx_msgs=0) > dovecot: Nov 03 05:52:01 Info: pop3-login: Login: > user=<joyce(a)obfusca.ted>, method=PLAIN, rip=::ffff:67.9.149.201, > lip=::ffff:zz.zz.zz.zz, TLS > dovecot: Nov 03 05:52:02 Info: pop3-login: Login: > user=<howard(a)obfusca.ted>, method=PLAIN, rip=::ffff:81.44.31.210, > lip=::ffff:zz.zz.zz.zz, TLS > dovecot: Nov 03 05:52:02 Info: POP3(howard(a)obfusca.ted): Disconnected: > Logged out top=0/0, retr=0/0, del=0/0, size=0 > dovecot: Nov 03 05:52:03 Info: POP3(joyce(a)obfusca.ted): Disconnected: > Logged out top=0/0, retr=3/163473, del=3/3, size=163419 > dovecot: Nov 03 05:52:03 Error: POP3(joyce(a)obfusca.ted): mbox sync: > Expunged message reappeared in mailbox > /var/mail/vhosts/obfusca.ted/joyce (UID 1449 < 1455, seq=2, idx_msgs=0) > dovecot: Nov 03 05:57:02 Info: pop3-login: Login: > user=<howard(a)obfusca.ted>, method=PLAIN, rip=::ffff:81.44.31.210, > lip=::ffff:zz.zz.zz.zz, TLS > dovecot: Nov 03 05:57:03 Info: POP3(howard(a)obfusca.ted): Disconnected: > Logged out top=0/0, retr=0/0, del=0/3, size=0 > dovecot: Nov 03 06:02:01 Info: pop3-login: Login: > user=<joyce(a)obfusca.ted>, method=PLAIN, rip=::ffff:67.9.149.201, > lip=::ffff:zz.zz.zz.zz, TLS > dovecot: Nov 03 06:02:02 Info: pop3-login: Login: > user=<howard(a)obfusca.ted>, method=PLAIN, rip=::ffff:81.44.31.210, > lip=::ffff:zz.zz.zz.zz, TLS > dovecot: Nov 03 06:02:02 Info: POP3(howard(a)obfusca.ted): Disconnected: > Logged out top=0/0, retr=0/0, del=0/0, size=0 > dovecot: Nov 03 06:02:02 Info: POP3(joyce(a)obfusca.ted): Disconnected: > Logged out top=0/0, retr=3/163461, del=3/3, size=0 > dovecot: Nov 03 06:07:02 Info: pop3-login: Login: > user=<howard(a)obfusca.ted>, method=PLAIN, rip=::ffff:81.44.31.210, > lip=::ffff:zz.zz.zz.zz, TLS > dovecot: Nov 03 06:07:02 Info: POP3(howard(a)obfusca.ted): Disconnected: > Logged out top=0/0, retr=0/0, del=0/0, size=0 > dovecot: Nov 03 06:12:01 Error: POP3(joyce(a)obfusca.ted): mbox sync: > Expunged message reappeared in mailbox > /var/mail/vhosts/obfusca.ted/joyce (UID 1455 < 1458, seq=2, idx_msgs=0) Dovecot version: [jhg@helios ~]$ rpm -q dovecot dovecot-1.0-0.beta8.2.fc5 The MTA is postfix, and this is the first time this has ever happened. I made a copy of the mbox file, and find that it's over a megabyte long. Checking the postfix maillog I find that only three messages arrived for that user in the hour preceding the start of this behavior (all SPAM). No other users are affected, and I can't see anything obviously wrong in the mbox file. Could a bad message cause this?

[Dovecot] Server-side mail archiving - possible dovecot lda feature?
by Charles Marcus 03 Nov '06

03 Nov '06

Hi Timo, I have a question on the feasibility of adding the capability directly in dovecot LDA (or maybe this wouldn't be the correct place?) to provide a server-side mail archiving feature. What I'd like is a simple way to define a maildir, ie: vmail/archive/$user/Inbox and vmail/archive/$user/Inbox.Sent And then have the dovecot LDA deliver a copy of all mail (incoming and outgoing) to this archive folder. Is the dovecot LDA the best place for this to go? Or would an entirely new plug-in be more appropriate? My boss may be willing to pay to have this capability added. I have investigated other third party solutions, but I would prefer something that is tightly integrated with dovecot. I look forward to your response... -- Best regards, Charles

by Paul Aguirre 03 Nov '06

03 Nov '06

Hi all, I have instaled dovecot 1.0.rc10, and my configuration works fine if I get the mail with Evolution mail client, bu if I try to use outlook to get mails the authentication fail and I can't pass through the logon window. The maillog appear this message: dovecot: pop3-login: Disconnected: rip=192.168.0.22, lip=192.168.0.1 My dovecot configuration is: protocols = pop3 ssl_disable = yes mail_extra_groups = mail protocol imap { } protocol pop3 { pop3_uidl_format = %v.%u } protocol lda { postmaster_address = postmaster(a)example.com } auth_username_translation = "@." auth default { mechanisms = plain passdb pam { } userdb passwd { } user = root } dict { } plugin { } any idea to solve. thanks Paul

[Dovecot] Last connection date/time
by Luigi Rosa 03 Nov '06

03 Nov '06

Hi, in an installation of Dovecot I need to know when each user made his/her last POP3 connection in a maildir environment. The date of which of the index files maintained by Dovecot can I use to get this information? Thanks. Ciao, luigi -- / +--[Luigi Rosa]-- \ Left-Handers have rights too.

[Dovecot] any idea why the mail downloading is slow?
by LeVA 03 Nov '06

03 Nov '06

Hi! I'm using rc10, but had this problem with previous releases too. Not sure if this is a dovecot problem, but I can not think of anything else. The mail downloading with pop3 is ~very slow, approx. 20 Kbyte / sec. no matter how many mails I've got in my mailbox, or how big are the mails. My ISP provides me a dedicated 100mbit line, and everything else works as fast as expected eg. http, ftp, scp... The OS is OpenBSD 3.9-stable and the system is not under heavy load at all. I've tried to turn off TLS but there was no change. Is the pop3 protocol this slow by design or there is something wrong with my setup? Thanks! Daniel -- LeVA

[Dovecot] CRAM-MD5 auth broken with postgresql passdb?
by Chris Laif 03 Nov '06

03 Nov '06

I'm currently experiencing a problem which has already been described by Jonathan in http://www.dovecot.org/list/dovecot/2006-August/015501.html If I use CRAM-MD5 auth with passwd-file as a backend (Thunderbird client) everything works fine (MD5-hashes have been shortened for readability): dovecot: auth(default): password(bob(a)foo.bar,10.0.0.123): Credentials: f12c884ba3cc82.. dovecot: imap-login: Login: user=<bob(a)foo.bar>, method=CRAM-MD5, rip=10.0.0.123, lip=10.0.0.234 My passwd file contains a line like this: bob@foo.bar:{HMAC-MD5}f12c884ba3cc82.. If I change to postgresql-based passdb, PLAIN auth works (!) and CRAM-MD5 does not work: dovecot: auth(default): sql(bob(a)foo.bar,10.0.0.123): query: SELECT 'bob(a)foo.bar' AS user, '{HMAC-MD5}f12c884ba3cc82..' AS password dovecot: auth(default): password(bob(a)foo.bar,10.0.0.123): Credentials: dovecot: auth(default): cram-md5(bob(a)foo.bar,10.0.0.123): password mismatch Please note the ultra-simple SELECT-statement (I've tried other combinations as well - no success). sql.conf setting is "default_pass_scheme = HMAC-MD5". Dovecot version 1.0.rc10. In the postgresql-based example the "Credentials:" variable is empty. I wonder if this is a bug in dovecot. Please let me know if you need any further information to resolve this issue. Thanks, Chris (As a side not I still do not understand how CRAM-MD5 auth is able to work without a plain text password, but that's another story. If it works with an HMAC-MD5 hash in a passwd-file backend it should work with the postgresql-db backend as well.)

[Dovecot] quota question
by Jakob Curdes 03 Nov '06

.. maybe a silly one, but how does the user get notified when he is over quota? Did not find anything in the docs. Is there a general IMAP way to do this or what else ? Yours JC

[Dovecot] Check plugin loading for LDA and dovecot-sieve
by Will Prater 03 Nov '06

03 Nov '06

Hello, I found this thread: http://www.dovecot.org/list/dovecot/2006- September/015955.html and have successfully compiled and installed cmusieve plugin. How does one test to make sure its being loaded? It's not parsing my sieve files in the users homes and I'd like to first check if the plugin is being loaded, since I am getting no errors about it. Thanks
