This really isn't correct. Rodney is trying to set up a BACKUP email
server. This is done all the time by responsible ISPs and knowledgeable
corporations running their own email servers. The first step (which I
assume Rodney has done) is to create a second MX record with a lower
priority. When an SMTP server looks up the MX records, it will try to send
the mail for that domain to the primary email server first (as defined by
the MX records). If that fails, and other MX records exist, the SMTP server
will attempt to send the mail to the mail servers as defined by the
remaining MX records. Rodney only wants to be a secondary "MX" server.
*IF* the email server software is capable of performing secondary services
(and I can't answer this because I don't use Sambar's email functions) then
it should be easy enough to set a configuration option *someplace* that
tells the server to accept all inbound mail for xdomain.com (whatever) and
store it until the primary server is reachable. When the primary is up
again, the secondary server simply sends the mail to it as it would *any*
other pending mail. This is not "open relaying" and should not require
special authentication.
Like I said, I don't know if Sambar has secondary domain logic built in or
not, but this is a generally accepted practice and follows the RFCs for
email routing.

Subject: [sambar] relay {10}
Guys,
I don't understand what relay domains has to do with MX.. All relay domains
is saying is let anyone with that domain in their from to send mail(SMTP)
through my server.. What Rodney is wanting to do is MX which means he wants
to receive the mail.. In that case Rodneys mail server has to recognize the
message as a Local Domain, and then he has to route it to a local mailbox..
Now, after he gets the message he has to figure out how to get the mail over
to his buddies machine once his buddies machine is back up and running.
Now first thought for this, I would think his buddy would just run some
fetchers that constantly pull from Rodneys mailboxes, however, in this case
you would not ever want the users doing pop3 to Rodeys box because
potentially users would be stuck there(dns) while their mail is on the other
server.
Another wild hair I could pull out is if both Rodney and his friends mail
servers were DNS servers(ns1,ns2).. Each with "different" mx and smtp
settings, so that if one of them were down, the other DNS server would give
different IP info to smtp and pop3's.. The downside to this is those DNS
cache resolvers in win2k world resulting in the same downside as the
previous paragraph.
SMTP relaying(outbound) is easy.. The receiving part is where the pain is.
