What I'm looking for should be relatively easy. All I want to do is setup something VERY small for Ubuntu that will allow me to use the mail() function in PHP from my web server (/var/www/). I don't want anything complex. I have a firstname.lastname@example.org type of email setup so if it is necessary, I can use that as a reply-to address. But I just want the ability to send mail, NOT receive any at my web server. Thanks
By the way, I've tried exim4 (btw, which setting should I pick, if it's possible to do what i want?), and I've tried ssmtp, but have had no luck with ssmtp. Thanks.
