Hi all,

This is the first time I use the dovecot mail list so I’m sorry if I forget something.

My problem is that for some reason I can get public mailboxes to work. I have setup the directory Public, the folders and the cur,tmp and new folder in them:

Public | |- .office3 | |- cur |- tmp |- new |- dovecot-acl

Here is my dovecot conf:

2.2.13: /etc/dovecot/dovecot.conf

OS: Linux 3.14.32-xxxx-grs-ipv6-64 x86_64

auth_default_realm = xxx.com auth_mechanisms = plain login mail_gid = vmail mail_home = /home/vmail/%d/%n mail_location = maildir:~/Maildir mail_plugins = acl mail_uid = vmail 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 namespace { list = yes location = maildir:/home/vmail/xxx.com/Public:INDEXPVT=~/Maildir/Public prefix = Public/ separator = / subscriptions = yes type = public } 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 = separator = / type = private } passdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } plugin { acl = vfile sieve = ~/.dovecot.sieve sieve_before = /etc/dovecot/sieve/dovecot.sieve sieve_dir = ~/sieve } postmaster_address = postmaster@xxx.com protocols = " imap lmtp sieve" service auth { unix_listener auth-client { group = Debian-exim mode = 0660 user = Debian-exim } } service imap-login { inet_listener imap { port = 0 } inet_listener imaps { port = 993 ssl = yes } } service lmtp { unix_listener lmtp { mode = 0666 } } ssl = required ssl_cert = </etc/dovecot/xxx.com.pem ssl_key = </etc/dovecot/private/xxx.private.pem ssl_key_password = yyyyyyy userdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } verbose_ssl = yes protocol lmtp { mail_plugins = acl sieve } protocol imap { mail_plugins = acl imap_acl }

The error I’m getting is that LMTP can’t deliver to office3@xxx.com because the user could not be found. (I’m using LDAP authentication for the users)

Mar 9 19:50:43 mail spamd[21021]: spamd: connection from localhost.localdomain [127.0.0.1]:56531 to port 783, fd 5 Mar 9 19:50:43 mail spamd[21021]: spamd: setuid to Debian-exim succeeded Mar 9 19:50:43 mail spamd[21021]: spamd: checking message <FBFE5FE1-A3C3-4C3D-8BD9-1C2AAC90BE17@xxx.com> for Debian-exim:107 Mar 9 19:50:44 mail spamd[21021]: spamd: clean message (-1.1/5.0) for Debian-exim:107 in 0.5 seconds, 1611 bytes.

So as I see it LMTP tries to see if the user exists and fails because there is no such user (which is true, the LDAP object office3 has a different base).

I’m not sure but should Dovecot skip this and check the Public folder first before checking LDAP?

Another part of my setup is Exim4.

Here is the transport part: dovecot_lmtp: driver = lmtp socket = /var/run/dovecot/lmtp return_path_add #maximum number of deliveries per batch, default 1 batch_max = 200

And here is the auth part:

dovecot_login: driver = dovecot public_name = LOGIN server_socket = /var/run/dovecot/auth-client

setting server_set_id might break several headers in mails sent by authenticated smtp. So be careful.

server_set_id = $auth1 .ifndef AUTH_SERVER_ALLOW_NOTLS_PASSWORDS server_advertise_condition = ${if eq{$tls_in_cipher}{}{}{*}} .endif

dovecot_plain: driver = dovecot public_name = PLAIN server_socket = /var/run/dovecot/auth-client server_set_id = $auth1 .ifndef AUTH_SERVER_ALLOW_NOTLS_PASSWORDS server_advertise_condition = ${if eq{$tls_in_cipher}{}{}{*}} .endif

So any tips on how to fix this would be great.
