telnetでgmailへメールを送るコマンド(Bash)

Posted at 2016-04-16

telnetを使って、gmailのメールアドレスへメールを送ることが出来ます。（2016/04/15現在）
SMTPサーバーの仕様が変われば、使えなくなる可能性があります。

Bash

(echo "EHLO example.com"; sleep 1
echo "MAIL FROM: <example@example.com>"; sleep 1
echo "RCPT TO: <example@gmail.com>"; sleep 1
echo "DATA"; sleep 1
echo "Subject: Subject"; sleep 1
echo "From: example@example.com"; sleep 1
echo "To: example@gmail.com"; sleep 1
echo ""
echo "Content"
echo ""
echo "."; sleep 1
echo ""
echo "quit") | telnet gmail-smtp-in.l.google.com 25
