Re: Postfix “RCPT from unknown Sender address rejected: Domain not found" error after SpamAssassin installation

[Reindl Harald]

"NOQUEUE: reject: RCPT from unknown Sender address rejected: Domain not found" is clearly Postfix and "reject_unknown_sender_domain" while you should post *all* loglines for that transaction and not just one stripped line

Hi,

I tried different senders and I always receive the same error. More of this, if 
I change back:

#smtp           inet  n       -       n       -       -       smtpd
smtp            inet  n       -       -       -       -       smtpd -o 
content_filter=spamassassin

to

smtp            inet  n       -       n       -       -       smtpd
#smtp           inet  n       -       -       -       -       smtpd -o 
content_filter=spamassassin

all comes back to working well.

So, I suppose a SpamAssassin related problem. Can I provide other useful 
information?

Thank you,

Are you sure the sender domain is legit and doesn't have a misspelling?

Is DNS on the box working?  I would conjecture this is much earlier in the 
discussion phase with postfix and spamassassin isn't even involved in this 
issue.
