No.

I'd use virtual(5) aliases, perhaps in conjunction with a
$recipient_delimiter, to alias each one to a system user.
main.cf :
mydestination = localhost, localhost.$mydomain[, ... ]
### I use "-" if planning to use delimited addresses in the real
### world, because a lot of stupid web forms reject "+" in email
### addresses
recipient_delimiter = +
virtual_alias_maps = hash:/etc/postfix/virtual
[ ... ]
/etc/postfix/virtual :
supp...@example.com support+example.com@localhost
supp...@example.net support+example.net@localhost
supp...@example.org support+example.org@localhost
[ ... ]
Create a system user, "support", and use .forward files:
~support/.forward+example.com :
"| /var/www/bin/support/support.php example.com"
~support/.forward+example.net :
"| /var/www/bin/support/support.php example.net"
~support/.forward+example.org :
"| /var/www/bin/support/support.php example.org"
Refer to:
http://www.postfix.org/virtual.5.html
http://www.postfix.org/aliases.5.html
http://www.postfix.org/local.8.html
http://www.postfix.org/postconf.5.html#recipient_delimiter
http://www.postfix.org/postconf.5.html#virtual_alias_maps
Other choices include pipe(8) and transport(5) maps, but this seems
simpler to me.
