Prohibit users sending unauthorized e-ma

By kywong ·
Application: MS Exchange 5.5 w/SP3

I want to block user sending unauthorized e-mail address.

User can send e-mail to recipient which under global address book only!! (that means the user can't send to custom e-mail address)

How can I prohibit user to send unauthorized e-mail address?

P.S. e-mail means internet mail

Prohibit users sending unauthorized e-ma

Hi!

I don't think you can prohibit that on a per user basis.

You can setup a firewall that will only allow traffic on port 25 whitin your companys intranet, but then noone will be able to send or recieve mail outside of your company.

The whole point of an E-Mail server is to allow users to send mail anywhere.

When you create a new mail even if your users wouldn't be allowed to list the global adress list they could still just type any E-Mail adress in the TO field and the mail server will send it to that recipient.

There might be some third party addon that can do what you want but not exchange.

Get management to make it policy that they will be fired if it happens.

Set up a psuedo mail account. Call it Bad Users. Then go into Exchange and give it extra entries for the SMTP addresses you want to 'block' - intercept would be a better term - heh, heh - then when the users try to send to the address Exchange will resolve it internally first and send it to the Bad Users mailbox. Not only will this stop the mail from going to the unauthorized address, it'll give you a record of everyone who tries to send to it Once again proving your worth to your boss and onceagain proving that it SUCKS to be a user!!!
Admins rule.... heh heh heh

You can't do this in Exchange. You're best bet is a filtering tool on outbound messages that either monitors content or restricts by domain .
I would not try to restrict user to the GAL. Why? You'll be swamped with request to add users to the GAL on a daily basis.

Check out Mail Essentials [www.gfifax.com]. They make a good filtering tool [also adds content checking, virus scan, etc.]. I'm not sure what the granularity of the reporting tool but I believe it provides info on total bytes as well as reports on outbound by destination as well.
