Block inbound mails to a specific mail address

St4ckOv3rflow

Hello sonicwall community,

we have a mail address that is just for sending out mails ( -> no-reply address). External people should not answer to those mail address and should get a NDR that we rejected the incoming mail.

What is the best way to solve this problem on our ESA?

@St4ckOv3rflow You should make sure that teh reply to address in the email is NULL which will prevent anything inbound to that address. But in casse something does come in the easist option is to create a policy filter to bounce the email back to the sender and you can configure a custom message.
