Submission config being ignored
by William Edwards 12 Dec '19

12 Dec '19

I'm having trouble setting up submission with Dovecot proxy. The submission config seems to be getting ignored, but I'm probably doing something wrong. Expected behaviour: have messages sent to submission ports (25, 465) relayed to `submission_relay_host`. -- root@imapproxy1:~# cat /etc/dovecot/conf.d/20-submission.conf submission_logout_format = in=%i out=%o submission_relay_host = smtp.prorelay.nl submission_relay_port = 587 submission_relay_ssl = starttls submission_relay_ssl_verify = no service submission { } service submission-login { inet_listener submission_25 { port = 25 } inet_listener submission_465 { port = 465 ssl = yes } } -- What happens instead: Dovecot is attempting to send mail to the host specified in the passdb file: root@imapproxy1:~# cat /etc/virtual/xalys.nl/passwd test:$password.:8:8::/home/test.nl/test:/bin/false:userdb_quota_rule=*:bytes=0 proxy_maybe=y host=$ipaddr How do I get Dovecot to relay mail sent to submission ports to 'submission_relay_host'?

Duplicate e-mail with Dovecot and Sieve
by Claudio Corvino 12 Dec '19

12 Dec '19

Hi everyone, we have a duplicate e-mail problem with Dovecot 2.2.13 (LMTP as MDA) on a Debian 8 server. Our users are on external LDAP. We just need to setup a vacation responder (with Sieve) for our employees with a redirect to an alias (a distribution list), let's call it /LIST(a)domain.com/, that comprehends even the user that just activated the out of office. This generates a loop: when someone write to LIST(a)domain.com every user of the aforementioned distribution list receives a duplicate e-mail generated from the sieve script of the user with vacation responder active that contains the redirect to LIST(a)domain.com. We just tried activating the duplicate extension into sieve script but the redirected e-mail has a different MSG-ID and it's not recognized as a duplicate by the server. Our dovecot conf is: /# 2.2.13: /etc/dovecot/dovecot.conf auth_mechanisms = plain login default_vsz_limit = 512 M disable_plaintext_auth = no dotlock_use_excl = no info_log_path = /var/log/dovecot-info.log log_path = /var/log/dovecot.log mail_fsync = never mail_location = maildir:~/Maildir mail_max_userip_connections = 50 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 ihave duplicate mmap_disable = yes passdb { args = /etc/dovecot/dovecot-ldap.conf driver = ldap } passdb { args = /etc/dovecot/dovecot-ldap-archive.conf driver = ldap } plugin { sieve = file:/var/www/html/ooo/%n/script sieve_dir = /var/www/html/ooo/%n/ sieve_duplicate_default_period = 1m sieve_duplicate_max_period = 1d sieve_extensions = +vnd.dovecot.duplicate +notify +imapflags +vacation-seconds sieve_global = /etc/dovecot/sieve/ sieve_max_redirects = 10 sieve_user_log = file:/var/www/html/ooo/%n/sieve_error.log sieve_vacation_default_period = 1d sieve_vacation_max_period = 90d sieve_vacation_min_period = 5s } protocols = imap pop3 lmtp sieve service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } unix_listener auth-master { group = vmail mode = 0660 user = vmail } user = root } service imap-login { process_limit = 200 } service lmtp { executable = lmtp -L process_min_avail = 5 unix_listener /var/spool/postfix/private/dovecot-lmtp { group = postfix mode = 0666 user = postfix } user = vmail } service managesieve-login { executable = /usr/lib/dovecot/managesieve-login inet_listener sieve { port = 4190 } process_min_avail = 10 service_count = 1 } service managesieve { executable = /usr/lib/dovecot/managesieve } ssl_cert = </etc/ssl/*xxxxxxxxxxxxxxxxxxxxxxxx* ssl_cipher_list = ALL:!LOW:!aNULL:!eNULL:!SSLv2:!RC4:!MD5:!DES:!EXP:!SEED:!IDEA:!3DES ssl_key = </etc/ssl/private/*xxxxxxxxxxxxxxxxxx* userdb { args = /etc/dovecot/dovecot-ldap.conf driver = ldap } userdb { args = /etc/dovecot/dovecot-ldap-archive.conf driver = ldap } protocol lda { auth_socket_path = /var/run/dovecot/auth-master hostname = *xxxxxxxxxxxxxxxxx* info_log_path = /var/log/dovecot-lda.log log_path = /var/log/dovecot-lda-errors.log mail_plugins = " autocreate sieve quota" } protocol lmtp { info_log_path = /var/log/dovecot-lmtp.log log_path = /var/log/dovecot-lmtp-errors.log mail_plugins = " autocreate sieve quota" postmaster_address = postmaster@*xxxxxxxxxx* } protocol sieve { info_log_path = log_path = mail_max_userip_connections = 10 managesieve_implementation_string = dovecot managesieve_logout_format = bytes=%i/%o managesieve_max_compile_errors = 5 managesieve_max_line_length = 65536 }/ An example of user sieve script is: /require ["vnd.dovecot.duplicate","copy","fileinto","vacation-seconds"]; # rule:[Outofoffice] if true { vacation :addresses "xxxxxxx(a)domain.tld" :subject "Automatic Reply" text: / /<Text here> . ; fileinto "INBOX";/ / redirect "LIST(a)domain.com";/ /}/ Please could someone give us support on the matter?

Lmtp redirection to other backend server
by Marc Roos 11 Dec '19

11 Dec '19

I have currently a working local delivery working ok on 2 backend servers. The backend servers use slapd/nslcd/nscd for local accounts. If I enable proxy=yes in the lmtp config section, I am getting this error 'auth: Debug: passdb out: FAIL#0111#011reason=Configured passdbs don't support credentials lookups' which is obvious because I do not have a passdb. I am not sure if it is possible to get this value from the system environment eg. nslcd/nscd, without the need to configure some separate ldap lookup in dovecot? Or do I really need to configure a ldap lmtp lookup just for this host attribute? What would be an efficient solution?
