Given that "man mail" shows no mention of things like SMTP (the Internet mail protocol), and talks about things like sendmail, I strongly suspect this is the case. Note that it does not explicitly require "sendmail" the program; it simply requires a Mail Transfer Agent (MTA) that emulates the sendmail interface. One such program (and the one that I use) is "Postfix". Most alternatives tend to be easier to configure than sendmail, IMO. > (2) can 'mail' be setup to send mail through my isp? No, but your MTA can, and 'mail' by extension. In Postfix, this would be the "relayhost" option. In sendmail, I think it's called a "smarthost" or similar.
