discussion of two documents on SMTP relaying:
having separate MSAs for roaming users vs. fixed users seems like poor
design. it's another set of MSAs to maintain, another set of
instructions to provide, another configuration detail users have
to get right, another source of calls to tech support. I don't know
why we should encourage it.
I can see a set-up where MSA.Domain resolves via the local DNS when
connected to DOMAIN's LAN Network (ie: When the user is getting
connectivity from that ISP) while the Internet Facing DNS Servers
supply a separate MSA Server Farm address. Which MSA Server Farm you
connect to is dependent on what Connectivity you currently have and
the selection is automatic without the user needing to alter the MUA
Parms.
