mail server: just send mails out, but not receive
I understand that the "mail" command in linux sends an email using the default send mail programme (I think that is called an MTA, but correct me if I'm wrong).
What I need is for my server to send emails (to clients, and myself) regarding system stats etc etc.
I don't need the server to accept emails, do spam filtering, have Horde installed or anything. ALL I need it to do is to send emails out the way.
I don't think I want to use Perl for this, because I need to use the PHP "mail" command (which I think works the same as the linux one in that it uses the default MTA to send emails).
So, I need some advice of the programmes which I need to install. If possible, I would like to use Exim because I've heard that it is easy to configure.
If I just installed an MTA, would that be enough to use the mail command?
Thank you so much, in adance
