Hello,

I have a virtual mailbox setup of Postfix+MySQL and I would like to run a script every time mail comes in for foo@domain.tld. How do I go about doing that? I've read and googled and trialed-and-errored to no success with this one.

Please advise
Arturo

i want to know about when i type in browser http://www.google.com and as i press enter the brower opens the web http://www.google.com.pk why and how it is ? i think it checks my ip address and redirects, if any one know its configuration please tell me

Checkout the following links/search:

http://www.postfix.org/postconf.5.html - Search for "check_recipient_access"
http://www.postfix.org/access.5.html - Search for the "FILTER" action

For reference: This is how I call Spamassassin. Note the call to spamc in master.cf. You could change that to be your script.

# cat /etc/postfix/mail.cf
smtpd_recipient_restrictions=
...bunch of restrictions
...check_recipient_access=/etc/postfix/SAfilter

# cat /etc/postfix/myfilter
mydomain.com FILTER SAfilter:spamassassin

# cat /etc/postfix/master.cf
SAfilter unix - n n - 10 pipe
flags=Fq
user=spamassassin
argv=/usr/bin/spamc -f -x -e /usr/sbin/sendmail -i -f $sender $recipient
