multi instance postfix with 2 IP address and 2 sending domains

Hello,

I have configured server to support 2 sending IP addresses with
corresponding 2 sending domains. DKIM, SPF, reverse hostname works
correct, primary and secondary instances are setup with corresponding
myhostname and smtp_helo_name. smtp_bind_address also configured correct
on both instances. But for some reason Gmail or Microsoft Outlook
detecting second domain as spam but first one working well. How to debug
this? I can provide any details if needed.

Best regards,

Postfix + saslauthd SASL With Kerberos (FreeIPA) unable to send mail

Hello I just finished setting up FreeIPA with Dovecot + Postfix + Saslauthd.
I can easily access to mails using imap via dovecot with gssapi
authentication and postfix also delivering mails very well. But I cannot
send email from postfix using gssapi authentication (plain and login
authentication working fine) because saslauthd is not specifying realm when
requesting service from freeipa domain.

warning: SASL authentication failure: GSSAPI Error: Unspecified GSS failure.
