I'm configuring postfix on centos. some action is to be done when email recieved on email@example.com. Is it necessary to specify an alias (it's always the same sh script) for each id or I can somehow specify it one time for all emails of class firstname.lastname@example.org?
The only way you could do that once time is using regex but for security reasons regex are not allowed in the aliases and virtual user table. http://www.postfix.org/PCRE_README.html
