I have two Exchange 2010 SP3 CAS servers. They are front-ended by several
load balancers. In front of that we have a spam and a/v appliance that filters

appliance reported that it could not send messages to Exchange as no
resources were available on the Exchange side.
Looking at the CAS servers, I saw entries in the app logs: "receive

And the second issue is because the apparently source IP address of your
servers has changed; your relay configuration is now incorrect. You either need
to the do the filtering at the LB or direct the internal users to the internal

You are brgeneral and this hit your system there?
If that is correct I don't see that as a relay, I see it as someone spoofing

(port 587). You relay for authenticated users only. It sounds like the

Just a thought here, but most IPs allow their users some form of webmail
access. Can't they use that to access their personal email?

open relay allowed?
Hello all,
Any of you guys here that is familiar with the RFC rules for email?
Are we as a public school allowed to send mail from other domains?
The reason I'm asking it is an internal discussion we have here.
We are moving to exchange 2010 and the old open interna
open relay is never a good idea
and your server will just end up on a blacklist if the server remains open for
relay. That point should be enough of a reason to justify closing the open
relay.

I don't think RFC rules have exceptions for public schools. Seems to
their home ISP for personal email
and your systems for school related stuff.
When I ran a school IT network we just made sure each use used their home ISP.
Now when I was a student we had no external email access allowed, so every
email had to be bounced of an open relay
