The setup has historic reasons. However I can eliminate reverse.rrr.com completely and replace it by host.xxx.com. Right now reverse.rrr.com has an A-record pointing to the host's ip address.


Eliminating reverse.rrr.com completely and replacing it by host.xxx.com would be good. This will help.

Also if I look up the A record for reverse.rrr.com either locally or at aaron.ns.cloudflare.com there isn't one. This will be moot if you replace reverse.rrr.com with host.xxx.com.



What is the output from `postconf -n`?


alias_database = hash:/etc/aliases
alias_maps = hash:/etc/aliases
append_dot_mydomain = no
biff = no
compatibility_level = 2
inet_interfaces = all
inet_protocols = all
local_recipient_maps = proxy:unix:passwd.byname $alias_maps hash:/var/lib/mailman3/data/postfix_lmtp
mailbox_size_limit = 0
message_size_limit = 0
mydestination = localhost, localhost.localdomain, arvak

This needs to include $myhostname

Also, including reverse.rrr.com would help with your current setup, but instead you should just eliminate reverse.rrr.com completely and replace it by host.xxx.com.
