Hi all
I'm getting emails blocked by a mailserver that send me the message below.
How to know which policy I'm breaking?
I checked my IP on many tools and my IP or domain aren't include on any
blacklist.
Looking for any other evidence for this rejection I found an entry when
check MX domain record on DNSstuff. There are an entry on a DRBL gremli.ru
list. Checking the type entry I got the description text: spamtrap hit. Is
this entry responsible for the rejection?
My server is a CentOS with cPanel, all cPanel RBLs activate (include
Barracuda), port 25 is blocked and all users have to authenticate to send
email.
Thanks for any help,
Ronaldo Luiz
