lmtp and recipient_delimiter
by Juri Haberland 16 Mar '20

16 Mar '20

Hi list, I have a small problem with recipient_delimiters contained in usernames. Recently I have extended recipient_delimiter from "+" to "+-" in both Postfix and Dovecot (using lmtp) and now any user that have a '-' in it's username can't receive mail anymore, because lmtp truncates the localpart after the '-' and of course can't find the first half in the user database. To illustrate: given an account "foo-bar(a)example.com", I get the following log entry from postfix: Mar 9 09:31:43 batleth postfix/lmtp[6196]: 9A7BA33E005B: to=<foo-bar(a)example.com>, relay=batleth.sapienti-sat.org[private/dovecot-lmtp], delay=20, delays=20/0.01/0.01/0.08, dsn=5.1.1, status=bounced (host batleth.sapienti-sat.org[private/dovecot-lmtp] said: 550 5.1.1 <foo-bar(a)example.com> User doesn't exist: foo(a)example.com (in reply to RCPT TO command)) Is there any way to tell lmtp to first look for <user><delimiter><extension> and if that fails look for <user> only (the reverse order would be ok, too)? Thanks in advance, Juri doveconf -n: # 2.3.10 (0da0eff44): /etc/dovecot/dovecot.conf # Pigeonhole version 0.5.10 (bf8ef1c2) # OS: Linux 4.4.0-174-generic x86_64 Ubuntu 16.04.6 LTS ext4 # Hostname: batleth.sapienti-sat.org auth_default_realm = sapienti-sat.org first_valid_uid = 115 imap_idle_notify_interval = 29 mins last_valid_uid = 115 mail_location = maildir:/srv/vmail/%Ld/%Ln managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date index ihave duplicate mime foreverypart extracttext namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { autoexpunge = 180 days special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { autoexpunge = 365 days special_use = \Trash } prefix = INBOX. separator = . } passdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } plugin { sieve = file:~/sieve;active=~/.dovecot.sieve } protocols = " imap lmtp sieve" service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } } service imap-login { inet_listener imap { address = 127.0.0.1 ::1 } } service lmtp { unix_listener /var/spool/postfix/private/dovecot-lmtp { group = postfix mode = 0600 user = postfix } } service pop3-login { inet_listener pop3 { port = 0 } } ssl_cert = </etc/letsencrypt/live/sapienti-sat.org/fullchain.pem ssl_cipher_list = EDH+CAMELLIA:EDH+aRSA:EECDH+aRSA+AESGCM:EECDH+aRSA+SHA384:EECDH+aRSA+SHA256:EECDH:+CAMELLIA256:+AES256:+CAMELLIA128:+AES128:+SSLv3:!aNULL:!eNULL:!LOW:!3DES:!MD5:!EXP:!PSK:!DSS:!RC4:!SEED:!ECDSA:CAMELLIA256-SHA:AES256-SHA:CAMELLIA128-SHA:AES128-SHA ssl_dh = # hidden, use -P to show it ssl_key = # hidden, use -P to show it ssl_prefer_server_ciphers = yes userdb { args = uid=postfix gid=postfix home=/srv/vmail/dovecot_state/%Ld/%Ln driver = static } protocol lmtp { auth_username_format = %Lu mail_plugins = " sieve" } protocol imap { mail_max_userip_connections = 20 }

Catchall with UserDB?
by Ferenc 15 Mar '20

15 Mar '20

Hi! I've set up Postfix with virtual users. I wanted to get Dovecot and LMTP up and running with Passwd-file UserDB, which they do, but I can't figure out how to make use of a catch-all. Currently, mail to joe(a)example.com needs Joe to be in the Passwd-file. I would like anyone(a)example.com to go to Joe's mailbox, or actually mail to @example.com should go to Joe. But what do I put in the Passwd-file? I need this for several domains. Like @somedomain.org should go to jim(a)example.com and @anydomain.net to jake(a)example.com. I've googled myself silly but I cannot find the it. Everybody is hooked on a sql userdb which seems like overkill to me. With Postfix doing local delivery this is rather trivial. With Dovecot LDA I got it working by using virtual_alias_maps and the right parameters in master.cf. But with LMTP I'm stumped. cheers, Ferenc

imap-hibernate won't start
by Webservice 14 Mar '20

14 Mar '20

I can't get imap-hibernate to fire up. The process is not starting, and there are no clues in the logs. I tried several users/groups, but nothing happens (although I see plenty of IDLE imap-connections). Even mode 0666 didn't work. I'm on Slackware (no FreeBSD), built from source with ./configure --with-mysql My systems runs with a virtual user, and imap-processes are run under vmail vmail 21840 0.0 0.0 14076 2596 ?

Or an option so I can debug?

Pigeonhole v0.5.10 release notes
by Aki Tuomi 11 Mar '20

11 Mar '20

Hi! We made a mistake of releasing pigeonhole with wrong release notes, so please find the correct release notes here. Also if you are using `--without-dovecot-install-dirs`, you must use `--with-moduledir`. Otherwise the Makefile gets broken. v0.5.10 2020-03-06 Aki Tuomi <aki.tuomi(a)open-xchange.com> * imap_sieve_filter: Change result action logging to include IMAP UID - vacation: Addresses were compared case-sensitively.

Dovecot Imap-Proxy: openssl_iostream_handle_error

Hi, I'm running Dovecot 2.3.9-2 as an IMAP/POP3 Proxy in front of several Dovecotbackends. No Director, only static routing to the backends of each user.

how to create Drafts, Junk, Sent, Trash folders after user already created
by chayes＠afo.net 10 Mar '20

10 Mar '20

Hello Dovecot, Do to a misconfiguration, I have a bunch of users who do not have the standard folders. I can create a routine to cycle through the users and look for the folders and run a command if there is one. Is there a way to create the proper namespace for a user after the user has already been created? Thanks in advance.
