Mail Relay/Spam

[lkamenir]

I am having problems where people are apparently using my mail server to send spam.. and the sender (reply addr) is a know address on my server.. so relay (auth required) is allowing it..

Any recommendations?

Which mail server are you using?

 

[lkamenir]

Mail Enable Pro (w/ Plesk 7.5 - Windows)

 

[siren@]

Open up the mail enable administrator go to Connectors, right click on SMTP and go to properties

Click to tab relay and make sure "Allow Local Sender Address" is unchecked.

If I do that, won't that turn off the ability for me to send legitimate mail from local senders?

No, those are set by IP for the server. Then for hosting clients (outlook) they use SMTP Authorize.
