I've encountered a mail server that won't connect to a mail server that 
lacks STARTTLS.  OpenVMS TCP/IP Services lacks STARTTLS.   Mail servers 
are a moving target.   That STARTTLS "fun" is in addition to DKIM and 
the rest of the "fun" that can arise here, too.   I don't know off-hand 
if Multinet includes STARTTLS, but I'd be surprised if it didn't.   How 
it manages its certificate store is another (related) matter.
