Blocking external email sending/recieving for a pupil

[flyinghaggis]

We've been asked to set up a pupil with an email account so they can send/recieve from email other pupils/staff in the school but cannot send/recieve email externally to addresses outside our domain.
We're running MS Exchange 2003 SP1. I'm sure there's probably an option hidden somewhere to do this but I can see an easy way to do it without breaking something else!

Does anyone know the best way (assuming it's possible) to set this up?

TIA

You need to use a Transport rule.

we do this by forwarding all external email to a mail relay.
the relay automatically creates lists of aliases from AD - if we want to block student email we do it there.
the mail relay also does virus and spam filtering (and could do content filter but isn't in this case)
setup is Sendmail/Mailscanner and a perl script

IIRC in Exchange 2003, on the properties of the "Internet SMTP connector" (under routing group connectors, NOT the SMTP virtual server), delivery restrictions, "reject mail from".

I've never had to do this myself, so test first.

just one of the fantastic additions in Exchange 2007. Unfortunately, many of the changes are so major that we'll all need re-training before we upgrade, and you just know that will never happen...

c'mon - most MTA's can do this already - so learn one of those and save on some licensing

uhm, just dont give them an internet routable email address?

e.g. spannerkid@yourschool.local.

Exchange can do most of what other MTAs are capable of, but the way to do it isn't always obvious. Same as most servers really...if you know the system it's easy, if you don't it's hard.

Why pay to learn a whole new system when what you've already got works fine after you've found the right option?

You don't have to pay to learn, most of the Internet is free

[Geoff]

Yes but exchange costs money. Especially in CALs. Other systems do not have this issue.

Cheers Lord_Edam,

This has done the trick.
