We run dnsreport.com on a regular basis to check all our virtual domains and suddenly we find now errors on mail for postmaster and abuse on all domains

ERROR: One or more of your mailservers does not accept mail to postmaster@domain.name. Mailservers are required (RFC822 6.3, RFC1123 5.2.7, and RFC2821 4.5.1) to accept mail to postmaster.

WARNING: One or more of your mailservers does not accept mail to abuse@domain.name. Mailservers are expected by RFC2142 to accept mail to abuse.

Both mail addresses postmaster and abuse used to be system-wide aliases forwarded to root in /etc/aliases.

Until recently none of virtual domains had these error and warning.

Just happened that also recently cPanel upgraded to latest Stable version (WHM 9.4.0 cPanel 9.4.1-S65 RedHat 9 - WHM X v3.1.0 ).

Also recently we upgraded Apache to 1.3.31. Running Exim 4.34-60).

Anybody with the same problem or with a solution??

Tks in advance,
Robby Fokkens
