problem with dovecot/lmtp
by Dan LaSota 03 Mar '15

I am getting this in my errorlog for postfix/dovecot Mar 2 16:42:14 mail postfix/error[5074]: A689580F236: to=<root(a)mail.example.com>, relay=none, delay=21420, delays=21420/0.05/0/0, dsn=4.4.1, status=deferred (delivery temporarily suspended: connect to mail.example.com[private/dovecot-lmtp]: Connection refused) From my reading, I believe this has something to do with virtual_transport which I have set to: virtual_transport = lmtp:unix:private/dovecot-lmtp The socket file, exists: [root@mail ~]# ls -l /var/spool/postfix/private/dovecot-lmtp srw-------. 1 postfix postfix 0 Mar 2 09:14 /var/spool/postfix/private/dovecot-lmtp But I'm a little stumped as how to proceed. The only thing I think I understand is that postfix is trying to talk to dovecot-lmtp and dovecot-lmtp is refusing the connection. Am I reading that correct? What can I do about it?

Postfix - dovecot-lda -> Permission denied
by Wöltje, Marcus 02 Mar '15

02 Mar '15

Hi erveryone! I'm trying to run Postix and Dovecot on a Mac OS X, but somehow, it doesn't work. I probably messed up the privileges or something else. Hopefully someone of you, can help me figure it out. So far, Postfix is delivering the mail into ~/Maildir. But as soon as I add the line: mailbox_command = /Applications/Server.app/Contents/ServerRoot/usr/libexec/dovecot/dovecot-lda in /etc/postfix/main.cf I get the following entry in the mail.log. Feb 27 16:08:02 Nils-iMac.local local[53237]: fatal: execvp /Applications/Server.app/Contents/ServerRoot/usr/libexec/dovecot/dovecot-lda: Permission denied Feb 27 16:08:02 Nils-iMac.local postfix/local[53236]: B246837BE40: to=<marc(a)localhost.local>, orig_to=<marc@localhost>, relay=local, delay=1185, delays=1185/0.01/0/0.01, dsn=4.3.0, status=deferred (temporary failure.

Re: Dovecot & LDAP Take #2: Authentication failed and logging
by Paolo Cravero 02 Mar '15

02 Mar '15

This is the user DN: > cn=Klara Fall,ou=People,dc=[domainname],dc=de According to your Dovecot configuration > auth_bind_userdn = cn=%u,ou=People,dc=**[domainname]**,dc=de if you login with "klarafall" it will be expanded into cn=klarafall,ou=People,dc=[domainname],dc=de which is not the correct DN for Mrs Klara. So if you login with "Klara Fall" it should work, but that will probably mess up the things on Dovecot filesystem. I am strongly against setting a static DN when dealing with LDAP authentication. LDAP servers are optimized to serve search requests, so let yours do the job. Allow Dovecot to lookup the correct DN based on the attribute you supply (uid) and then authenticate. This should be achieved if you comment out the auth_bind_userdn line. Paolo Cravero

mdbox attachment errors

userdb passwd-file default_fields uid not expanding %variable
by Tim Jones 02 Mar '15

02 Mar '15

Hi all, I'm trying to set up a very simple shared mail server, where each 'domain' is a system user, i.e. 'example.com' is a real user with /home/example.com/, a uid of 5001 (and gid 'example.com' of 5001). Each domain\user has their own maildir inside their home, and a plain passwd-file with the virtual mail users associated with that domain. Version & config info: # dovecot -n # 2.2.13: /etc/dovecot/dovecot.conf # OS: Linux 3.2.0-4-amd64 x86_64 Debian 7.8 auth_mechanisms = plain login auth_verbose = yes disable_plaintext_auth = no mail_location = mbox:~/mail:INBOX=/var/mail/%u namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = } passdb { args = username_format=%n /home/%d/mail_users driver = passwd-file } protocols = " imap lmtp pop3" ssl = no userdb { args = username_format=%n /home/%d/mail_users default_fields = uid=%d gid=%d home=/home/%d/mail/%n mail=maildir:/home/%d/mail/%n driver = passwd-file } Every time I try to authenticate via imap, I get the error > <timestamp> <host> dovecot: auth: Fatal: passwd-file userdb: Invalid uid: %d If I put fixed a uid and gid in the userdb default_fields line: > default_fields = uid=example.com gid=example.com home=/home/%d/mail/%n mail=maildir:/home/%d/mail/%n authentication passes without a problem, but of course, only for users of example.com. Checking the wiki (http://wiki2.dovecot.org/UserDatabase#Userdb_settings) clearly states that the default_fields values support %variables, so I'm not sure if I'm missing some other config required for this to work.

Require certificate for external clients
by Karol Babioch 02 Mar '15

02 Mar '15

Hi list, I'm currently looking into ways of making use of client certificates. I want to force external clients (i.e. anything outside the local subnet) to use client certificates. It is my understanding that this in itself can be achieved with the "ssl_require_client_cert" setting. However, I also want local clients (i.e. anything from a specific subnet) to be able to authenticate by the usual means (i.e. password-based). As far as I know dovecot is not able to operate on multiple ports, as stated in the FAQ [1]. The redirect approach, which is also mentioned there, is of no help to me, because in my case I would need a different setup on both ports. Other suggestions [2] won't work in my case either. I probably could get away with using "imaps" for external clients, while using "imap" (without SSL) for internal ones. Having said this, I don't quite like the idea, especially since the traffic might pass through some potentially unsecure networks and I don't want to bother with VPN/SSH tunnels for that purpose. A native SSL/TLS solution would be very much appreciated. Is there a (recommended) way to do this? Thanks in advance. Best regards, Karol Babioch [1]: http://wiki.dovecot.org/QuestionsAndAnswers#Is_it_possible_to_have_Dovecot_… [2]: http://www.dovecot.org/list/dovecot/2010-November/054804.html

If they differ, you can can copy those files to another config directory (e.g. conf-d/* -> conf-2.d/), modify the snippets that differ, then include this alternate set of configurations !include conf-2.d/* > Thanks for your suggestion.

dsync panic
by Greg Rivers 02 Mar '15

02 Mar '15

As per <http://wiki2.dovecot.org/Migration/Dsync>, I'm running the following command on a local dovecot server to replicate email for a single user from a remote IMAP server: doveadm -D \ -o imapc_host=remote.imap.server \ -o imapc_user=gcr \ -o imapc_password=XXXXXXXX \ -o imapc_list_prefix=IMAP \ -o imapc_features="rfc822.size fetch-headers" \ -o mail_prefetch_count=20 \ -o mail_fsync=never \ backup -R -u gcr imapc: This runs fine for a while and successfully copies quite a lot of mail, but always aborts before completion with the following error: dsync(gcr): Panic: file mail-transaction-log.c: line 271 (mail_transaction_log_rotate): assertion failed: (file->locked) The exit code is 262. Does anyone know why this might happen or how to fix it? -- Greg Rivers

You can run two instances of dovecot, each on a different port or multi-homed listening address. You can share libraries, binaries, log files, but use separate configuration files, specifying different ports/addresses/ssl-configs/auth/access parameters. Then you can fire them both up dovecot -c /dovecot/etc/dovecot-1.conf dovecot -c /dovecot/etc/dovecot-2.conf That's the rough sketch of how to do it. Joseph Tam <jtam.home(a)gmail.com>
