One of the sites hosted, a phpbb site, when running a single all-one-server, when someone registered it sent out an activation email and it worked great. Now that I'm running on the multiple server setup, I cant seem to get the site to send emails via the Email Server regardless if I point it do the dns name or the just the internal IP address. Do I need to install Sendmail or something on the webserver in order for it to send the email from the webserver via the email server? If not, how do I get this working again?
