I am attempting to send some emails through my ISP (Comcast) via sendmail on my FC3 machine.
I have managed to successfully create a Comcast email address and a corresponding local user name (Example: firstname.lastname@example.org
and a user account called 'admin' on my Linux machine).
Here's my problem:
I can create an alias in the /etc/aliases file that automatically sends local mail to email@example.com
, but since sendmail expands aliases, if the "terminal originator" of the message is, for example 'root,' the mail is undeliverable because there is no Comcast account called 'firstname.lastname@example.org.'
So my question is, how can I make it so that any system processes that run as root (and consequently send alert emails as root) will be able to send mail out using that 'admin' account that DOES have a corresponding Comcast email address?
I'm sorry, I know this is very convoluted, if you need clarification, please ask.
