| We want to deliver outgoing mail with the following strategy:
| 
|  1. Attempt to deliver mail directly to destination.
| 
|  2. If (1) fails for *any* reason (452 DNS blacklisted, 550 DNS 
|     blacklist, DNS failure, or TCP timeout) then treat this as a 
|     temporary failure and retry immediately using the ISP mail 
|     spooler.


Hi,

As discussed yesterday, the fundamental problem is many sites will accept
your mail (2XX) and then deliver it into a spam folder, which the user may
or may not read in a timely manner, or indeed, at all. You have no way of
knowing if this has happened.

Best to get a real server:
