[SOLVED] Virtual users in Postfix/Courier - execute script Is it possible to execute command for received message in Postfix configuration described in http://www.howtoforge.com/virtual-u...-courier-mysql-and-squirrelmail-debian-wheezy ? Should I add command to transport table? Adding to /etc/aliases seems doesn't work UPDATE Solved a problem, maybe in not reliable way, but it works. 1. Add new virtual map to /etc/postfix/virtual: email@example.com robot 2. change owner of /etc/postfix to postfix user & execute postmap /etc/postfix/virtual 3. create alias to command in /etc/postfix/aliases robot: "|/path/to/script" 4. add hash:/etc/postfix/virtual to virtual_alias_maps (before mysql 5. restart postfix Now, all messages to firstname.lastname@example.org forwarded to script.
