I use e107 CMS for my website hosted on a Linux Mandrake server in my room...
During registration I want it to be able to send a validation email users have to activate for their account to work. It has settings for me to enter a SMTP server and user/pass information. How can I setup my Linux box to be a SMTP server? That way I don't have to use my local ISP to relay the mail?
Do I need to install sendmail or something similar?
