SMTP
Simple Mail Transport Protocol. This is how E-MAIL is transferred on the Internet.
Wikipedia:SMTP∞ states:
It is a client-server protocol, where the client transmits an email message to the server. Either an end-user's email client, a.k.a. MUA (Mail User Agent), or a relaying server's MTA (Mail Transfer Agents) can act as an SMTP client.

SMTP connections are used by email client applications to transfer the message to the internet for delivery.
SpamCop Email service does not support remote SMTP connections*. To send email using SpamCop's SMTP services, you must log into the
WebMail application and send the message directly from that connection.

Remote SMTP service is currently be tested as a beta service - see SMTP-AUTH
Spammers would love to sign up for SpamCop and send
spam just to discredit the service. You need to use your
ISP's SMTP server or check out
Jeff G.'s Hotspot SMTP-Auth Provider Status Report∞ for other SMTP services.
SMTP-AUTH extends the protocol by including an authentication process.
