Absolute Must Have Setup

I assume you already have for your outgoing mail server ALL the following:

- forward and reverse (A and PTR) DNS entries point to the same name

- reasonable EHLO/HELO from your server

- SPF implemented

- closed relay, ALL outgoing emails are coming from authenticated users only

- monitoring in place, at any stage you know what happens on the server (especially the size of the queues, any bounce backs)

- ALL outgoing emails filtered through Anti-Spam.

- abuse@ and postmaster@ are valid email addresses and are being monitored

 

In addition it is highly recommended to implement the following:

- DKIM (DomainKeys Identified Mail) with it's DNS entry

- DMARC (Domain-based Message Authentication, Reporting & Conformance)
