Helo you,
I try to build a mail server based on Centos 7, postfix and dovecot 2. My backend is a Samba4 ad-dc.
I tried a lot and I don't know what else I could try.I'm new to this mailing list so please forgive me if I don't give right information or anything
Samba4 ad-dc is up incl. dns. Win10 Client joined domain and authentication works.
Postfix is up and checks against ldap whether recipient address exists. It takes mail via telnet and queues them. But can't give it to dovecot.
my master.cf locks like that:
[root@mail1t postfix]# cat master.cf smtp inet n - - - - smtpd submission inet n - - - - smtpd -o smtpd_enforce_tls=yes -o smtpd_tls_security_level=encrypt -o tls_preempt_cipherlist=yes pickup fifo n - - 60 1 pickup cleanup unix n - - - 0 cleanup qmgr fifo n - n 300 1 qmgr tlsmgr unix - - - 1000? 1 tlsmgr rewrite unix - - - - - trivial-rewrite bounce unix - - - - 0 bounce defer unix - - - - 0 bounce trace unix - - - - 0 bounce verify unix - - - - 1 verify flush unix n - - 1000? 0 flush proxymap unix - - n - - proxymap proxywrite unix - - n - 1 proxymap smtp unix - - - - - smtp relay unix - - - - - smtp showq unix n - - - - showq error unix - - - - - error retry unix - - - - - error discard unix - - - - - discard local unix - n n - - local virtual unix - n n - - virtual lmtp unix - - - - - lmtp anvil unix - - - - 1 anvil scache unix - - - - 1 scache maildrop unix - n n - - pipe flags=DRhu user=vmail argv=/usr/bin/maildrop -d ${recipient} uucp unix - n n - - pipe flags=Fqhu user=uucp argv=uux -r -n -z -a$sender - $nexthop!rmail ($recipient) ifmail unix - n n - - pipe flags=F user=ftn argv=/usr/lib/ifmail/ifmail -r $nexthop ($recipient) bsmtp unix - n n - - pipe flags=Fq. user=bsmtp argv=/usr/lib/bsmtp/bsmtp -t$nexthop -f$sender $recipient scalemail-backend unix - n n - 2 pipe flags=R user=scalemail argv=/usr/lib/scalemail/bin/scalemail-store ${nexthop} ${user} ${extension} mailman unix - n n - - pipe flags=FR user=list argv=/usr/lib/mailman/bin/postfix-to-mailman.py ${nexthop} ${user} dovecot unix - n n - - pipe flags=DRhu user=vmail:vmail argv=/usr/local/libexec/dovecot/deliver -f ${sender} -d ${user}@${nexthop} #smtp inet n - n - 1 postscreen #smtpd pass - - n - - smtpd #dnsblog unix - - n - 0 dnsblog #tlsproxy unix - - n - 0 tlsproxy postlog unix-dgram n - n - 1 postlogd

Hi,
No expert, but:
We always use the postmap utility to check that the right mailboxes are actually found:
postmap -q test@test.loc ldap:/etc/postfix/ldap-config.cf
And perhaps show us your postfix main.cf?

Hi Phil,
phil, 20.02.20:
I try to build a mail server based on Centos 7, postfix and dovecot 2. My backend is a Samba4 ad-dc.
I tried a lot and I don't know what else I could try.I'm new to this mailing list so please forgive me if I don't give right information or anything
Samba4 ad-dc is up incl. dns. Win10 Client joined domain and authentication works.
Postfix is up and checks against ldap whether recipient address exists. It takes mail via telnet and queues them. But can't give it to dovecot.
You told postfix to hand over the messages to dovecot using dovecot-deliver. I 'm not sure which privileges are used/needed by dovecot in this case. Your dovecot has been configured to use uid/gid vmail/vmail, and maybe this causes problems.
I'd give lmtp a try. Just define a "transport" for postfix which hands over messages for "local delivery" to dovecot using lmtp. From my point of view, this makes life easier qith dovecot running with vmail/vmail.
You should take another look at dovecot's userdb settings as dovecot's last log line states "Userdb lookup failed".
After having taken a closer look, I'm just wondering about your user_filter = (mailRoutingAddress=%u)
There is no such attribute (MailRoutingAddress) in your ldapsearch results. My conclusion: dovecot is looking for something non-existant - and can't find it ;-)...
I'd also recommend using a preceding "%L" to make dovecot use lowercase characters, e.g.: user_attrs = uid=%Lu,=home=/mail/%Ld/%Ln This can make life easier sometimes...
Kind Regards, Christian
