The answer (unofficial -- I do not work for Wollongong) is that
Wollongong is based on PP from ISODE, and PP is a "protocol
independent switch" which includes an RFC987/1148 gateway in its
processes, and it can switch both X.400 and SMTP mail, as well as
convert between the two, all in a single queue.

PP uses MTA and gateway technology that vendors can only ignore at
their peril.  Cheers...\Stef
