hey guys,
we had a spam attacker get on our exchange server apparently last weekend. we disabled smtp relay and that seemed to stop it, but apparently it is also causing some of our clients to not receive email from us. We get NDR messages back. Can anyone help with this? I'm at a lost at this point.
Thanks!

Please refer the following articles.

I hope the above two articles should solve your problem related to spam.

REG. emails not received by your clients check if your domain is blacklisted. If yes then remove it from where it has been blacklisted
