Hi - I have an older CentOS box that has very limited use, but it does have to send short Email notifications. I currently use the well-known sendemail.pl perl script, but it has known issues with SSL/TLS, and the last SMTP provider available to me that doesn't require SSL/TLS is upgrading. So I'm looking for a very simple command-line Email SMTP client (equivalent to cmail on windows), that will let me type something like

somemailer.exe -s (server/username/password/port(465)) -subj <subject> -from <me> -to <me>.

There are 1/2 dozen self-contained options on Windows, I have to believe there's one available on Linux, but I'm clearly not using the correct search terms .

Thanks Very Much!
