Setup

Things most mail servers demand/require to ensure delivery:

• rDNS of sender IP matches sender domain and/or SPF record
• SPF record allows mail server to send mail for domain – see: wwwhttp://en.wikipedia.org/wiki/SenderPolicyFramework
• Setup DKIM/DomainKeys on DNS server + email server – see: our guide for DKIM and Postfix

Test

Send emails to either (or both) of these emails to test SFP records & other things

• [email protected]
• [email protected] (the email will bounce, look for test ="pass" in the response error)
