I've heard of and installed the ">254 concurrencyremote" patch... to allow
about 400 concurrent remote connections, BUT I haven't heard of this other
patch you mention... sounds like it might increase speed considerably...
got any more info on it?

Actually, I was kind of under the impression that since the dedicated
email server would be ONLY doing email and absolutely nothing else, that
even a 900Mhz CPU with 128Mb RAM and 30Gb HD would suffice, since it would
only act as a conduit (and it has good bandwidth btw). No email is
actually received there either... it just sends OUT email (the Qmail
servers only relay their mail to that server).
Wouldn't this be the case?
