Hi,

I have a user who always sends messages to the email "robert _vinicius2013@hotmail.com".

As you can see it is wrong, it has a blank space, and this email is always stuck in the Postfix queue.

How do I block sends to this email or block sends to emails with blank space?

Thanks for listening

Re: Block sending to certain email

then empty the postfix queue with that email destination.
i don't know why it is in the queue at all, since it should be delivered and end up as a bounce message.

is the mail manually sent, or do you think it is a breached account and the mail is sent trough this?


edit:

this command should clear the mailq for you

mailq | tail +2 | grep -v '^ *(' | awk  'BEGIN { RS = "" } { if ($7 == "comproised@mail.com") print $1 }' | tr -d '*!' | postsuper -d -

Hi buddy,

Is the mail manually sent.

Every month the user sends along with other emails and he simply recorded this one wrongly. I could just ask him to fix it, but if in the future he makes a mistake again the problem will persist.

The problem shouldn't even exist, since undeliverable mails should just cause a bounce and don't persist in the mailq forever

for now, yeah asking him to fix it would't be the worst for now, but troubleshooting why this odd behaviour occours should be investigated further

do you have any maillogs of the failed delivery?
