No. I only have SIMS on my network. I could potentially press an ASIP
server into service for mail, but the controls there are even more
limited than SIMS. All I'm trying to achieve with the secondary is a
place for mail addressed to "[EMAIL PROTECTED]" to go if my primary goes
down. The secondary should "hold" the mail and keep trying to pass it on
to my primary until the retry time elapses (obviously set to a
ridiculously high level) or until the primary is back online.
It is not my intention that my users should "exchange" mail via the
secondary at all.

How does the number of sending and receiving channels affect the
secondary's functionality in terms of merely "passing" mail on to the
primary?

But see, I DO want it to accept incoming mail... and then pass it to the
primary. I think, though, that several others have answered this issue
sufficiently. I will probably duplicate my blacklist and "error" routings
just to cut down on the junk.

Once again my tiny brain is having a hard time fitting this in. So long
as "pecandeluxe.com" is on one side of the "mail equation" (either
FROM:[EMAIL PROTECTED] or TO:[EMAIL PROTECTED]), it's not a "relay",
right? So, even though the secondary is getting e-mail from some ip in
Outer Mongolia, if the destination is [EMAIL PROTECTED], it will try to
deliver the mail on to the primary, correct? (I know, I know... this
should be "Mail Administrator 101", but some of us have to learn these
things as we go).
Now, in the "Sending Options" section of SMTP Settings, do I choose
"Directly to Recipients" or "via Foreigh Mail Server" (with my primary as
the "foreign" server)? Or does is matter? Is all of this simply
controlled by the router setting:
pecandeluxe.com=pecandeluxe.com.smtp
I appreciate all of the comments I have received so far. They have really
helped. I know I'm gonna lick this eventually!
