[Web-cyradm] RegExp in Postfix Alias - Help!

[Jan Scholten]

I don't know what you try to achieve.. if you /dev/null them (however you would like to do that),
the mail is still sent to your box. (and then deleted).

Normally your server should reject the mails to unknown recipients in the beginning of the smtp dialog, which is the
prefered way to do it. (This does not work woith catchalls, cause catchalls are evil)

So what are you trying to setup in your alias table? The right way is: have every legal email
address in there and reject (not bounce) all other addresses.

so have sth like in postfix main.cf:

...
virtual_alias_maps = mysql:/etc/postfix/virtual.mysql
alias_maps = mysql:/etc/postfix/aliases.mysql
...
smtpd_recipient_restrictions =
                ...
                permit_mynetworks,
                permit_sasl_authenticated,
                reject_unauth_destination,
                ...
