From past discussion this seems to be SPF related, however as a
smarthost for an ISP in the UK we send email from lots of different
domains - the majority of which are owned by our customers. This makes
it difficult to mandate SPF records on the domains we send from.
I have some doubts they reject domains without SPF records, that would
reject a massive amount of legitimate emails while for a spammer, it's
easy to setup a permissive SPF.
I have had confirmation that this is the case
