Moving emails tagged as spam to the Junk folder
by Mika Leppänen 12 Sep '17

12 Sep '17

I am running Ubuntu 16.04. I am following this guide: https://wiki2.dovecot.org/HowTo/AntispamWithSieve. At the end when I try to compile the .sieve files, I get this error: sievec(root): Fatal: Plugin 'sieve_imapsieve' not found from directory /usr/lib/dovecot/modules/sieve. Does anyone know about this? I have dovecot-sieve installed and I'm using Postfix and Spamassassin. -- Mika Leppänen -- mika.leppanen(a)iki.fi

Re: Share Website certificate with SSL/STL Dovecot IMAP and Postifix SMTP

By "same pairs", I assume you mean key and certificate. Yes, just as long as you use the same Subject for all your services (e.g. "mail.yourdomain.com") or you have purchased a wildcard certificate e.g. "*.yourdomain.com" to authenticate "webmail.yourdomain.com", "imap.yourdomain.com", "smtp.yourdomain.com", etc.) Certificates do not authenticate services or protocols, but server names (typically).

Returning error response to the client from passdb (with dict protocol)
by Nagy, Attila 11 Sep '17

11 Sep '17

Hi, When using a passdb with (UNIX socket) dict protocol, I can return a JSON with fields. When I want to deny the user, I can send a JSON like this: {"fail":true} which yields (on POP) a friendly -ERR [AUTH] Authentication failed. Is it possible to return the response text itself? I want to tell the user why the authentication has failed.

Fail2ban 'Password mismatch' regex
by James Brown 11 Sep '17

11 Sep '17

I have turned on 'auth_debug_passwords=yes’ in dovecot.conf. I’m trying to get Fail2ban to detect this log line: Sep 11 15:52:49 mail dovecot[54239]: auth-worker(10094): sql(user(a)bordo.com.au <mailto:user@bordo.com.au>,::1,<L2xqieNYeM4AAAAAAAAAAAAAAAAAAAAB>): Password mismatch (given password: 2) I’ve added it as the last line of my dovecot filter regex: failregex = ^%(__prefix_line)s(%(__pam_auth)s($dovecot:auth$)?:)?\s+authentication failure; logname=\S* uid=\S* euid=\S* tty=dovecot ruser=\S* rhost=<HOST>(\s+user=\S*)?\s*$ ^%(__prefix_line)s(pop3|imap)-login: (Info: )?(Aborted login|Disconnected)(: Inactivity)? $((auth failed, \d+ attempts)( in \d+ secs)?|tried to use (disabled|disallo$ ^%(__prefix_line)s(Info|dovecot: auth\(default$|auth-worker$\d+$): pam$\S+,<HOST>$: pam_authenticate failed: (User not known to the underlying authentication$ ^%(__prefix_line)s(auth|auth-worker$\d+$): (pam|passwd-file)$\S+,<HOST>$: unknown user\s*$ ^%(__prefix_line)s(auth|auth-worker$\d+$): Info: ldap$\S*,<HOST>,\S*$: invalid credentials\s*$ ^%(__prefix_line)sauth: Info: sql$\S+,<HOST>$: (Password mismatch|unknown user)( $(SHA1 of given password: [0-9a-f]{5,40}|given password: \w*)$)?$ Have spent ages googling and trying different variations.

Is it possible to disable pipelining in imapc?
by Nagy, Attila 11 Sep '17

11 Sep '17

Hi, I've a broken IMAP server, which doesn't support pipelining and fails on dovecot's attempt to do this ([C] is dovecot's imapc, [S] is the IMAP server): [C] 24 LOGIN "user" "pass" [S] 23 OK [C] 25 SELECT "INBOX" [C] 23 UID FETCH 2 (INTERNALDATE) [S] 25 OK [S] 23 BAD No mailbox selected Sadly, fixing the server would be a hard task, turning off pipelining in dovecot's imapc (which already supports many workarounds for different servers) could be easy... ... except I can see no place to do this in imapc (only in pop3c and imap proxy, which I guess doesn't apply here). If I'm right, may I ask for a knob for such dumb servers? Thanks,

Per-user quota (passwd)
by Evgeniy Korneechev 11 Sep '17

11 Sep '17

Hello! We have passwd=pam, userdb=passwd. passdb { driver = pam #server was entered domain Active Directory } userdb { driver = passwd override_fields = home=/var/vmail/glu_vrem/%u } How can i use per-user quota? Only passwd-file? I tried: userdb { args = /etc/imap.passwd driver = passwd-file override_fields = home=/var/vmail/glu_vrem/%u } /etc/imap.passwd: administrator:*:95400500:95400513:Administrator:/home/DOM/administrator:/bin/bash::userdb_quota_rule=*:bytes=10G Authentication and quota - now OK. But doesn't work sending and receiving mail... postfix say 'Unknown user'... Is there "extra_field" in passwd-file for email?

doveadm expunge returns error code 68

Hi, i am running basically this from cron: /usr/bin/doveadm -v expunge -u * mailbox INBOX.Spam SENTBEFORE 90d /usr/bin/doveadm -v expunge -u * mailbox INBOX.Trash SENTBEFORE 90d /usr/bin/doveadm -v expunge -u * mailbox INBOX.Junk SENTBEFORE 90d Now i am experiencing that the first line e.g. expunging INBOX.Spam returns the error code 68. No syslog/Output whatsoever. I tried running with -vvv -D which gives me a lot of output (for all mailboxes) but still i am unable to pinpoint the problem. The later 2 commands return "0" as expected. Where does the error return code come from and what does 68 mean? Flo -- Florian Lohoff f(a)zz.de UTF-8 Test: The 🐈 ran after a 🐁, but the 🐁 ran away

Dovecot and Letsencrypt certs
by ＠lbutlr 11 Sep '17

11 Sep '17

So this morning at 4am I was awoken to my mail clients getting certificate errors for an expired certificate. I hopped on to the server and checked and… no, the LE certs renewed last month and are valid until November. After some moments of confusion I noticed that dovecot had been running since before the renewal, so I did a quick service dovecot restart which fixed everything. Should dovecot check for certs being refreshed? Or is this an artifact of my using symbolic links everywhere to point to the newest LE certs (which are themselves links the dehydrate script creates to point to the newest cert-1502534746.csr etc files? Should I just create a monthly cron to restart dovecot or is there something else? -- Apple broke AppleScripting signatures in Mail.app, so no random signatures.
