Exclude non-existing subdomains from checking

[Ludi Cree]

Hi all,

 

I would like to exclude non-existing subdomains from this rule:

 

"reject_unknown_sender_domain"

 

that I have on the end of my sender-restrictions here:

 

smtpd_sender_restrictions = check_sender_access
hash:/var/spool/postfix/plesk/blacklists, permit_sasl_authenticated,
reject_non_fqdn_sender, check_sender_access pcre:/etc/postfix/pcre_sender,
reject_unknown_sender_domain

 

So I put in my PCRE check before that:

 

/\.that-domain\.com$/                  OK

 

But I still get mail from @station.that-domain.com thrown out with:

 

4.1.8 Sender address rejected: Domain not found;

 

What am I missing here?

 

Greets,

Ludi
