Dear all
i've installed a postfix server with mysql support.
i've also set-up a custom filter script shell that calls spamc and
some other custom utils, this script cannot handle multiple
recipients, so i've set
filter_destination_recipient_limit = 1
The problem that i've experienced is that when i've got an entry like
this in the alias table:
+---------------------------+----------------------------------------------------------------------+----------------------+---------------------+---------------------+--------+
| address | goto
| domain | created
| modified | active |
+---------------------------+----------------------------------------------------------------------+----------------------+---------------------+---------------------+--------+
| forwar...@foo.com | i...@foo.com,f...@yahoo.it,f...@libero.it |
foo.com | 0000-00-00 00:00:00 | 2009-12-30 17:37:22 | 1 |
+---------------------------+----------------------------------------------------------------------+----------------------+---------------------+---------------------+--------+
Sending an e-mail to forwar...@foo.com causes that my script is called 4 times:
forwar...@foo.com
i...@foo.com
f...@yahoo.it
f...@libero.it
and the result is that i...@foo.com,f...@yahoo.it,f...@libero.it
receives the mail twice.

Is that behaviour correct?
How can i avoid to call the custom filter for forwar...@foo.com ?
Thanks
