[Shorewall-users] Enabling Postfix MX backup server and port issues

Thu, 24 Aug 2017 10:06:08 -0700 

Hi friends,
I'm enabling Postfix MX backup server and from that moment I see "mydestination" and "relay_domains" ip DROP(ped) 

"mydestination" is:91.205.175.213 (SERVER1)
"relay_domains" is:5.189.166.16 (SERVER2)


As here you can see:

Could you kindly suggest me if the problem was caused by Postfix and 
eventually witch port I should open?
