Implementing SPF into Postfix
by BAcidEvil from LinuxQuestions.org on (#54F0H)
Hello everyone.
So I ran one of those "how secure is my email server" and it came back 85% and I failed for 2 reasons; 1 was apparently my Reverse DNS/MX records are not the same, though I have verified over and over again and see absolutely no issues with forward/reverse dns and 2nd I do not have SPF integrated/utilized in my Postfix setup.
I have indeed done my google searches and I have learned a lot about it but am still lacking the confidence and clarity.
I see on Slackbuilds.org there is a perl-Mail-SPF package which I can use but there are layers of dependencies upon dependencies I would need as well, which I am fine with, but I wanted to make sure that was the appropriate path.
If that is my solution then I can run with it and comply but I was also wondering if there was a different legitimate path to take with implementing SPF into my Postfix.
Thank you !
