how to drop emails sent to non-existing account

[newbies]

Hi,

How can I set cpanel to drop any emails sent to non-existing account? Now my default account gets so many spam.

I know DirectAdmin allows to do that, but don't know how to do it in cpanel.

thank you for your help.

Setting your default account to forward to either :fail: or :blackhole: (both with the colons) will stop message delivery for all addresses not setup on your account.

:fail: will create a "bounce" message to the sender

:blackhole: will simply discard the message

Thank you very much for the info.

:fail: will create a "bounce" message to the sender

:blackhole: will simply discard the message

The cPanel exim configuration doesn't work that way now, with the verify = recipient rule that is in the standard ACL list

:fail: will give a RCPT rejection at the SMTP level and not accept the mail (no bounce)
:blackhole: will accpt the whole email and then discard during filter processing

So, :fail: is the way to go now since you don't even accept the email for delivery.

When did that happen?

At least 6 months ago

Then why is this happening?

I didn't read it indepth but because :fail: is rejecting the mail it never gets to the autoresponder, whereas with :blackhole: the mail is accepted and the auto-responder routine in exim is being picked up before the mail is thrown away. Something like that anyway, though I may have misread it

It does get to the autoresponder. The sender gets two messages, the auto response and a bounce.
