i am hoping someone has a list of do's and dont's to ensure outgoing has every possible chance of being delivered successfully.
the majority of my clients use exchange 2003 (as part of sbs2003) to send email. they receiv email via smtp.
a lot of them are getting bounce back with various messages such as (you do not have permission to send for this user, reverse dns lookup errors etc etc..
alsoa lot of customers emails (espcially when sent to hotmail/aol end up in junk email.
does anyone have a list of best practices to ensure this does not happen?
