Making a SMTP relay

I have managed to get port 25 opened on AWS, i’m running a mail server but I need to use one of the account as a no-reply account, and I want to add it to my services so they can automatically send emails.

Will this be possible?

Seems like I been blocked by spamphus, will try to get it unblocked.

Just create the no-reply account for you mail domain and if you don’t want to save received mail, select option to discard all mail when creating the account.


You are probably trying to use Spamhaus lists from an open DNS resolver.
