As a follow up to this, I've noticed IMail doing this more and more 
recently, it didn't happen as much as before we upgraded to 7.12.

However, I've caught it doing it again on a different domain

rsbmacdonald.co.uk

Which has only one MX record, but you can't ping it, and one of our 
servers has decided that it wants to send it to the a record on the domain 
name, which is unfortunatly our webserver that hosts the website, so it 
ends up going into a loop.

Any ideas on what IMail is playing at ?

the RFC say that the domain.name should not be tried if MX records exists 
but don't respond.

Since two MX records exists domain.name, Imail should not be sending to 
domain.name.

If the MX records don't exist, the RFC says to try this:

domain.name.  MX 0 domain.name.

no, but "there's a lot of (RFC) broken software out there".
