That's right, out of the box you can deliver
I know, and that's what we've been telling them.
But the fact we are going to prevent relaying is a limitation.
It doesn't have to be a limitation; the mail submission port can be used
(port 587). You relay for authenticated users only. It sounds like there
are several disparate
You could limit those allowed to relay to only your internal IP address
ranges. Then you would appease your users and not get your email server
listed on open relay blacklists. That would still not be the best
solution for the reasons others have mentioned, but it would be an
easily workable one
these
servers are allowed to send email for our domain. Not used a lot but often
enough I am surprised you have not had issues with that.
But let's change your terminology. You are not (I hope) running an open relay.
You are allowing authorized users/IP addresses to send email with any from
address

Not disappointed at all. You are only allowing internal users to use it. That
isn't an open relay by my definition. I would define that as open to
anyonelike open to the whole world/internet. What you are doing is very

Hello all,
Any of you guys here that is familiar with the RFC rules
or 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

Thnx for the answer!
Is the SPF something optional to configure
an 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.

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 internal relay
Subject: RE: Is an internal open relay allowed?
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?
