As I've discovered lately, "sendmail", while popular, is quite difficult to configure and/or customize. Ideally, I'd like to host an email relay or server, but one step at a time!
My extent of knowledge on MTAs and sending mail is thus:
That little magical command was enough to download, install, and configure sendmail, so my web applications could send emails across the globe.Code:sudo apt-get install sendmail
However, there doesn't seem to be any way to send mail TO the server in question. That is, if I send an email to firstname.lastname@example.org (mydomain.com being an example, of course), the sender (in this case, GMail) reports it as sent, but it never arrives in my local mailbox on /var/mail. So, I'm guessing that there needs to be some sort of configuring to be done on the server side so I can receive email?
Be blunt! If the answer is "sendmail is exactly what it says, it SENDS MAIL, you dolt!", then tell me!
I've been looking at other MTAs, like exim4... are they easy to set up?
