My mail server
I have been running my mail server for years using the ClearOS version of linux, it has worked very well with ClearOS security managing all the nasties coming in from the net. I get very little spam.
One observation though, I ran without a fixed IP address for years using dynamic DNS. It worked well except for one exception. The exception was occasionally email sent from my domain would bounce because some virus checkers check the IP and if it thinks it isn't a fixed IP address The email will be rejected. This was particularly annoying for me as my accountant was one of those affected.
Biting the hand that feeds IT
