How prevent to send SPAM mail from Exchange 2010
Hello I have an exchange 2010 server and somebody is sending mail from it to send SPAM, if i look the queue I have some mails without sender "<>".
And If the mail is correct, the name source message is "FromLocal" and if the mail is SPAM the name source message is DSN
Are there any computer, iphone or ipod infected and sending SPAM?
Is my exchange used to resend SPAM?
Can I prevent to send mail FROM "DSN" or without mail direcction?
Many thanks

Hello Exchange_Geek, I can´t find "AntiSpam tab" so i think is not installed. and I don't think Spam is sending to a particular sender.
Hello Alanhardisty, I've followed your link but for me is a little bit complex (and is very late in spain), and you are right, my exchange only have to accept from the relay, but I need the relay IP, and I don't know if is fixed, I 'll be ask it.
Otherwise, In the relay I've configured a list of usernames so only will be relay mails to these direcctions.
Thanks.

Has Exchange 2010 Standard any antispam included?
Maybe tomorrow pay the Eset Mail For Exchange (for AntiSpam filtering), but now I think is a good idea to do:
1- Prevent the NDR messages going back.
2- Prevent Exchange to receive any email for users who aren't part of you're AD.
Can you send me instructions to do these?
Many Thanks
