IMHO any ISP that blocks relaying based on the contents of the SMTP 
envelope needs a good kick up the backside.  They should relay based on 
source IP - if it's one of theirs, relay for it, otherwise reject it.  SMTP 
envelopes are trivially forged and should be considered unreliable for 
access control.

You should probably also use FEATURE(`accept_unresolvable_domains'), or it 
will tell you to go away for a while when it can't do a DNS lookup on your 
return address.  I keep running into this one at home - I used to have a 
permanent connection, but now have only dialup.  I miss my cable modem...
