SMTP Service & Spam

While trying to figure out DNS settings to ensure that the mail sent via our SMTP server does not end up in spam folder, I came across the following resources:

1. Fixing common DNS problems - Must read!
2. Sender Authentication - What To Do by Meng Weng Wong
   
3. 6 Simple Steps To Improving e-mail Deliverability
   
4. RFC2505 - Anti-Spam Recommendations for SMTP MTAs
5. Application Note: How to secure your mail system against third-party relay
6. Sender Policy Framework - Check out the SPF wizard
   

Cheers,
