Not that I know of, I think the information is pretty scattered across many articles, blogs, etc...
Here's a quick list off the top of my head through which may help you:
- Make sure you're not an Open Relay
- Make sure you have a valid reverse DNS
- Make sure you have valid SPF records setup (you should setup both TXT and SPF type records even if most places don't use the SPF type just yet)
- Configure Microsoft Sender-ID (goes along with SPF records)
- Configure DomainKeys and DKIM (I always use both as DKIM hasn't taken over 100% yet)
- Verify your IP address is not on any lists or in a bad IP neighborhood and if possible, has no previous bad reputation
- Install some form of bounce management, whether it be custom or a third-party software
After doing all of that, you should be in pretty good shape. The next most important thing, if sending any decent amount of mail is keep your sending pattern/volume consistent. Once you build up a good reputation as a sender, then apply for the various whitelists/bulk sender approval with the major ISPs.
Hope that helps
