used to restart the web server if certificates were
an easier way to test
whether mail from a certain domain will successfully get blocked that'd be

Thanks, I'll look into these. My goal is to silently discard all inbound

mail either to a flat file (similar to the proposed blackhole transport) or

Query the resolvers listed in /etc/resolv.conf directly, e.g.
dig @127.0.0.1 eurobank-direktna.rs a
dig @127.0.0.1 eurobank-direktna.rs mx
Alternatively try a public resolver in /etc/resolv.conf:
nameserver 8.8.8.8
or
nameserver 1.1.1.1

How does it send mail, a separate message per recipient, or
;, '127.0.0.1');
>> define('PHPMAILERPORT',2510);
This has been resolved offlist. There were some additional credentials
in phplist config that interfered.

Thank you Victor.
With help, I was able to "pipe" the mailing list to a port that bypasses
virus checking.

Hello
Can the domain certificates sign its sub domain?
For example, mail.a.com was signed by certs of a.com.
If so, does this make sense to DMRC of mail.a.com?
Thanks.

Yes.
If I understand the
wrong, but why should a resolver query
@ns1.eurobank.rs for eurobank-direktna.rs nameservers as
this information is already known. And it's not a subdomain
that might be delegated to another nameserver.
Best regards
