For developer machines, to redirect all outgoing mail to a single addres;
Create /etc/postfix/virtual-regexp with the following content:
/.+@.+/ email@gmail.com Edit /etc/postfix/main.cf and add regexp:/etc/postfix/virtual-regexp to the virtual_maps configuration. The end result might look like this in main.cf:
virtual_maps = hash:/etc/postfix/virtual, regexp:/etc/postfix/virtual-regexp Build the mapfile by typing:
postmap /etc/postfix/virtual-regexp This also requires a virtual.db to exist.
If it doesn’t create an empty file called virtual:
touch /etc/postfix/virtual
Then run the following to add the mapping
postmap /etc/postfix/virtual
Then just restart postfix!
/etc/init.d/postfix restart
