Is it possible that Dovecot act as a POP3-/POP3SSL-Proxy, "LDAP-authenticate" all user logins to a Windows 2003 domain controller and forward then all POP3-connects to a single Exchange 2003 server?

About the auth search the archives for auth and ad, e.g. you'll find "[Dovecot] Dovecot authenticating---> Active Directory Win2003". There you'll also find a discussion, why not do so :) but use kerberos instead.

Could someone give me some advices or a link for howtos for this solution?

Google "dovecot proxy ldap" and you'll find: "[Dovecot] Ldap Proxy" as well as "[Dovecot] proxy mode and ldap" quite easily.

The howto on www.dovcot.org (http://wiki.dovecot.org/HowTo/ImapProxy) does not fit in my situation because it prefere a mysql server and not a LDAP-server/domain-controller.

Actually, this is the doc, that applies to you. It says:

Have your passdb return: uid, host and proxy. nodelay and nologin is good, too.

http://wiki.dovecot.org/AuthDatabase/LDAP/Userdb Describes how to add static fields to a LDAP pass_attr/user_attr= query, e.g.:

pass_attrs = uid=user,userPassword=password,mailHost=host,=proxy=yes,=nologin=yes,=nodelay=yes

The syntax is roughly:

ldapAttribute=DovecotData=staticValue

if ldapAttribute is an empty string, the staticValue is used. It's kind of confusing sometimes.

Bye.
