Grr.  We have some users who have created domains on Dotster and 
forwarded all mail for those domains to their accounts on our system.  
I just thought the list might want to know the problems with Dotster:

1) They pool outgoing servers, so you have to at least turn on checking 
by subnet.
2) They do not retry in a timely fashion.  Retries seem to be more than 
5 hours more often than not - after the tempfail record expires by 

We have tried an experiment where we allow retries up to 25 hours.  It 
seems to compensate without allowing any significant quantity of spam.
