Good advice, thanks Eric. I'm about to jinx myself, but this solution was also suggested by Ipswitch (they have been very helpful and responsive)... both of our name servers are equally reliable, but since we've listed only one name server in the SMTP settings, we've not had any re-occurrence of the problem... about 6 days... I'm sure I've just cursed myself by saying that...
