Rejecting Invalid Users

[mag]

Hi,

Just started using EFA recently and all appears to be working well. I am planning on using this to replace an old, manually created mail filter.
The mail filter acts as a frontend to my postfix/imap server and one of the features I have is to reject invalid users. This is a setting in /etc/postfix/main.cf.

My question - can one modify the EFA files directly, namely add reject_unverified_recipient to the smtpd_recipient_restrictions line in the main.cf file?

If this file is created through the console/web configuration, how can one add this command to the postfix configuration?

Thanks

Yes.
