You can setup aliases for the ones you don't want going into the catchall mailbox , and deliver the mail to their own mailbox or send them off to another domain.

I just realized that this problem also happen to my cwp.
But as cwp doesn't create 1 to 1 alias as default when creating user/mailbox, this gonna be problem forever..

I hope, sql alias table for own mailbox will automatically created by cwp, with cwp Pro at least.

Found solution
first, create mysql map file, in my case i create :

Code: [Select]

/etc/postfix/mysql-virtual_alias_default_maps.cf
Will contain :

Code: [Select]

hosts = localhost
user = postfix
password = ************
dbname = postfix
query = SELECT username FROM mailbox WHERE username='%s' AND (active = '1' OR active = '3')
Then edit this file :

Code: [Select]

/etc/postfix/mail.cf
Find this line :

Code: [Select]

virtual_alias_maps = proxy:mysql:/etc/postfix/mysql-virtual_alias_maps.cf, regexp:/etc/postfix/virtual_regexp

Change to :

Code: [Select]

virtual_alias_maps = proxy:mysql:/etc/postfix/mysql-virtual_alias_default_maps.cf, proxy:mysql:/etc/postfix/mysql-virtual_alias_maps.cf, regexp:/etc/postfix/virtual_regexp
Restart postfix, and and create catch-all alias, will not ignore existing mailbox...

Worth mentioning that this rule will get lost if you rebuild postfix.

A better solution is (perhaps) to create aliases/forwarders for the accounts you don't want to be caught.

I.e. we have a catch-all for *@example.com, and accounts for john@example.com and sarah@example.com.

If you create a forwarder for each of john and sarah as follows, then these will take precedence over the catch-all rule and their mails will be delivered to their inbox instead of the catch-all.

john@example.com > john@example.com
sarah@example.com > sarah@example.com
