Local mail test on Ubuntu using postfix

If you are using Ubuntu and postfix there is nice little setting to test mail locally as if it was real.

You have to edit postfix confing file located at

/etc/postfix/main.cf

Add local cath-all address.

recipient_address

is you local user account that will server as catch-all inbox.

# local catch all address
local_recipient_maps =
luser_relay = recipient_address

Later you set-up local mail in Evolution (or any other mail client you are using) and send mail to any email address you are catching (what is this?) on you local machine.
