Rejecting non local mail for specific e-mail address

Hello!

I have a server with Debian Sarge, Postfix, Amavis, Spamassasin ... I would like to restrict one specific local e-mail address to receive emails which are not local or from our home domain. This e-mail address is actually an alias for large group of people (local e-mail accounts). I want only local users or users from our domain to be able to send email to group using this alias.

Thank you for ideas!

The parameter you need to change is "smtpd_recipient_restrictions".
By default, it's set to

Quote:

smtpd_recipient_restrictions = permit_mynetworks, reject_unauth_destination

You will want to change it to

Quote:

smtpd_recipient_restrictions = permit_mynetworks, check_recipient_access hash:/etc/postfix/recipient_access, reject_unauth_destination

The easiest way to set this parameter is to run the following, as root, from a command prompt (the alternative is to set it manually in main.cf).

Code:

postconf -e "smtpd_recipient_restrictions = permit_mynetworks, check_recipient_access hash:/etc/postfix/recipient_access, reject_unauth_destination"

Once that's done, you should create the file /etc/postfix/recipient_access, and it should contain the following:

Quote:

internaluser@whatever.com REJECT

Then, you need to run:

Code:

postmap /etc/postfix/recipient_access

Then reload postfix with

Code:

postfix reload

and you're all set.

Cheers

Thank you very much! This is the best answer I've got in a very long time.
Thanks again!

Did it work the way you wanted?

It works exactly as I wanted. It allows our local and VPN users to send mail to this address and rejects mails from other IPs!

Thank you again!!!
