Hello,

I want to send a mail to theo@example.com.
This user is not created in IRedAdmin but this is a gmail account (I created it in gmail)
However, if I send a mail to theo@example.com postfix seems to check if the user "theo" exists locally (in IRedmail)...

How can I disable this check?
I already tried to remove this: but it doesn't works..

Thanks!
