Setting up a mail server best practices to be recognized as legitimate

  • 772

What are the best practices to configure a mail server to have your mail recognized as legitimate non spam messages? Is it to use Domain Keys, Sender ID, Sender Policy Framework, some or all 3 of these together?

    There are a few similar mail related questions on SF already, however I'll answer this one as best I can. To avoid being recognised as spam, check:

    I have never required Sender ID, although as it's a Microsoft protocol I'd assume it's more important for Exchange/Live based mail - I have never had problems in this department without implementing Sender ID.

  2. I've found that disabling open SMTP relay, and having valid reverse DNS entries, is a good starting point.
