Postfix+cyrus imap integration with active directory

Dear Experts

Currently I am using Postfix+cyrus imap with openldap as authentication
backend.

Is it possible to use Active Directory as authentication backend for postfix
and cyrus ?

Can I manage users mailboxes in Active directory ?

Spoofing Emails to My Own Domain

Dear Experts,

I am facing a problem that someone is spoofing my domain address and sending
emails to my own domain users.

I have set valid SPF, DKIM, DMARC for my Mail server. How can I sort this
problem with postfix to stop this spoofing ?

If I filter emails based on SPF this also block many legitimate email with
spf not set properly.
