What do you do about email gateway/addresses in mixed environments
We're a medium sized, tight-budgeted, State University. Here's our
situation, we have faculty/staff email, about 1500 accounts on Exchange
2003, with email addresses like:
Lynne.Seamans@millersville.edu (firstname.lastname@millersville.edu)
We have our students (about 10,000 accounts) on a Solaris machine named
"marauder" using a web front end to access their email. Their email
address is abstudent@marauder.millersville.edu.
(firstImiddleIlastname@marauder.millersville.edu)
Not surprisingly, students are griping about their email address being too
long.
We don't want to move them over to Exchange, mostly for financial reasons,
so we are looking for a way to shorten their email addresses to
abstudent@millersville.edu (i.e., take the node name out).
So, what do other folks do?
We have had the following ideas:
(1) In the faculty/staff Exchange server, set the "Forward all mail with
unresolved recipients to:" field to Marauder (the student email server)
(a) Concern about performance hit on our Exchange Server forwarding all
the student email
(b) Concern about performance hit on solaris handing all true NDR's for
the organization
(c) concern about discrepancy in "From" address and perceived email
address.. meaning, a student could say "My email address is
abstudent@millersville.edu", but his "From" would be "abstudent
@marauder.millersville.edu". And that could cause problems especially will
mailing lists.
(d) If we do this, do i need a special connector?
(2) Build some kind of linux gateway for ALL mail to go through and somehow
query LDAP to decide which mailhost gets which email
(a) concern, honestly, whether we could actually pull this off
(b) same issue about email addresses, I think.
Any insights or "what we do" stories would be GREATLY appreciated :)

Re: What do you do about email gateway/addresses in mixed environments
Share the address-space.
http://support.microsoft.com/?id=321721
If you want Exchange to handle the inbound mail, and have performance
concerns, you can perhaps setup a lower-end box to be the bridgehead that
handles inbound mail and forwards to either the existing Exchange mailbox
server, or for recipients not existing on Exchange to the Solaris host.
Solution #1 would work for this - uncheck "This Exchange Organization is
responsible for all mail delivery to this address" in Recipient Policy for
@millersville.edu, and create a Connector for millersville.edu with the
Solaris box as a smarthost. Assign @millersville.edu email addresses to
recipients on the Solaris box.
Also note, this would make Solaris "authoritative" for the smtp domain and
it will be responsible for generating NDRs.

Re: What do you do about email gateway/addresses in mixed environments
I'll take door #1.
to address the concerns:
a. use a dedicated bridgehead. This can be a lower end box running
exchange standard.
b. sounds like it does that now for the bulk of the organization (all
students).
c. Rewrite the outbound address.

Re: What do you do about email gateway/addresses in mixed environments
Oh, cool, thanks, this sounds very promising :)
Couple clarifications:
(a) "bridgehead" .. i'm thinking i just build another exchange machine in
the site (it can be small), it doesn't hold any mailboxes, but is specified
in the connector to student email.
(c) so i have to route all OUTGOING mail from student email back through
the exchange (bridgehead?) to rewrite the email address? Is that right?

Re: What do you do about email gateway/addresses in mixed environments
Thanks, this is great info. I would not have known aobut the authoritative
check box!!
I asked this in another reply, but "bridgehead".. is what? just a small
machine built and joined to existing site that doesn't hold mailboxes but is
named in the connector to the student email box?

Re: What do you do about email gateway/addresses in mixed environments
That's correct - in your case, the description is appropriate.
Any Exchange server can be a Bridgehead for a Connector - whether it's a
mailbox server, a Front-End server, or a server dedicated to the Bridgehead
role (depending on the volume of mail... ).
