Hello list,

I'm really hoping someone can point me in the right direction on this.

I set up a server using Postfix with LDAP lookups to Active Directory. Postfix delivers to maildir. Dovecot IMAP and POP are working correctly using PAM Kerberos to authenticate via Active Directory.

I want to add spam filtering, so I'm trying to set up Postfix to use dspam which is then supposed to use Dovecot LDA to deliver messages to the mailbox instead of having Postfix deliver to the Maildir.

I can't get any deliveries to Dovecot LDA to get past passdb lookup. When I run

/usr/lib/dovecot/deliver -f bjarrett@garfield16.org -d bjarrett@metcalfexcavation.com

I get:

Dec 19 20:57:55 mxserver2 dovecot: auth: Debug: master in: USER#0111# 011bjarrett@metcalfexcavation.com#011service=lda Dec 19 20:57:55 mxserver2 dovecot: auth: Debug: password( bjarrett@metcalfexcavation.com): passdb doesn't support credential lookups Dec 19 20:57:55 mxserver2 dovecot: auth: Error: static( bjarrett@metcalfexcavation.com): passdb doesn't support lookups, can't verify user's existence Dec 19 20:57:55 mxserver2 dovecot: auth: Debug: master out: FAIL#0111 Dec 19 20:57:55 mxserver2 dovecot: lda: Error: user bjarrett@metcalfexcavation.com: Auth USER lookup failed Dec 19 20:57:55 mxserver2 dovecot: lda: Fatal: Internal error occurred. Refer to server log for more information.

so it doesn't even look like it's attempting to find the user. Here's my doveconf -n:

I have tried several configurations, but nothing seems to get me past the "passdb doesn't support.." errors.
