Don't use sendmail binary. It is slow. Use SMTP. And once you install TclLIB and want to be fancy take a look at the latest version of acs-mail-lite on HEAD. It allows you to define the SMTP parameters as ACS Parameters, allowing you to change mailservers on the fly in case your primary mailserver goes down. This is with username and password, so feel free to hammer against your E-Mail service provider and give them a hard time (just kidding). Currently it only supports complex send but obviously you could just copy past to ::smtp
