sendmail is a BSD program that is widely (though not exclusively) used as a mail transport agent in the *nix world. The module Mail::Sendmail is misnamed, as it doesn't use sendmail on a Windows box. Some *nix machines will use qmail instead of sendmail, for instance.
Update: I just read the Mail::Sendmail docs myself, and it sends out by SMTP if it can't find a local mailer. (The SMTP interface is not as advanced as in Net::SMTP.) | [reply] |
