Hey, I have a CentOS server running webmin and virtual min. I host a couple of websites and email accounts on there for personal reasons and it's more of a lab environment than anything else. However, I am having some issues with my emails, but mostly when someone is replying back to me.
This is what I am seeing in the maillog:
Code:

192.168.55.254 is my firewall. Maybe it is doing some smtp filtering perhaps?
