Thanks for the reply lammert - it sounds as if using
-all will be safe in my situation, as apart from the automated emails, the domain's email addresses are mostly used for receiving and not sending.
I have a supplementary question specifically relating to Hotmail delivery - what's the current situation with Sender ID? Would it be a good idea to create a dedicated TXT record in the Sender ID format for Hotmail, or should the SPF record suffice?
