I would like to setup dovecot (1.1.20) with LDAP virtual users, but I don't seem to understand how to get my sendmail to accept mail for the virtual users. (I am rather new to this, so I may have some misunderstandings)

I have followed - wiki.dovecot.org/HowTo/DovecotOpenLdap (OpenLDAP 2.3.43) and I think I have IMAP working for virtual users. I can connect to port 143, enter a username and password and it works.

Now I surmise I need to configure my SMTP server to accept mail for these LDAP virtual users, and deliver it appropriately. (The above HowTo doesn't address this step, from what I can tell)

I read - wiki.dovecot.org/LDA and wiki.dovecot.org/LDA/Sendmail (I'm using OpenBSD 4.7, which uses sendmail for MTA / SMTP server, sendmail version 8.14.3)

For sendmail.cf, I made the changes in my sendmail.mc file to include the dovecot mailer (calling /usr/local/libexec/dovecot/deliver), and compiled with m4 and installed the new sendmail.cf

For dovecot.conf, I edited the portions (abbreviated): protocol lda { auth_socket_path = /var/run/dovecot/auth-master } and auth default { socket listen { master {path = /var/run/dovecot/auth-master }}}

When I try to test this, (telnet www.example.org 25) If I try: MAIL TO:jdoe@www.example.org I get "User unknown" I see that if I try: MAIL TO:jdoe@example.org I get "Relaying denied" Either way it doesn't get delivered.

Thank you for any help. And if anyone knows a good basic tutorial for dovecot+LDAP+sendmail I would really appreciate it.

dovecot -n (de-identified, and yes I know SSL is disabled, after it all works I'll fix it)
