Forgive my ambiguity. By redundant SMTP I meant simply if all internal
clients are sending to the virus scanner as SMTP, and the scanner fails,
could the Imail smtp become the smtp, as in the MTA MX scenario. I think
you answered below.
Also.....excuse my ignorance...but what does ' vbg ' mean...I'm not up on
the hip new lingo you kids are using these days....and what is ' afaik ' ?
Either way....your help and contributions to the list are very appreciated.

Well, the SMTP client is process smart enough to step through the
DNS-provided, prefenced MX's until it finds an responsive
MTA. That's what I mean by "SMTP + DNS" providing MTA
backup/redundancy for mail delivery.
My question is, does Eudora's and Outlook's SMTP clients lookup the
MX records (more robust) or just the A record (and give up if that
MTA is dead) for the outgoing SMTP server?
"failover" is perhaps too grand a buzzword. Is the priortized list
of backup MX's "failover"?
What do you mean by "SMTP becomes redundant"?
