Request: Sendmail and telnet client

afu · 2004-05-30 03:16:50

Really would like sendmail as we use it at work. I am playing with exim now but 1 mta is enough to get lost in.

Also need a different telnet client. I see that there are 2 listed, but one of them requires xinetd (don't need - don't want), and the other (putty) dosen't play well with exim. Seems that putty creates a SMTP protocol violation when it connects to port 25 - exim dosen't respond. Seems to work with sendmail though.

Try ssh to port 25... it won't work.

Lifted from yolinux.com:

This is a sample of the dialog an e-mail client makes when connecting to an SMTP server for sending mail:

telnet server-name 25 - SMTP communicates on port 25. See: /etc/services
HELO your-domain - This identifies the source of the mail.
HELP - List the SMTP commands that are supported. (Included FYI and not part of a typical dialog)
MAIL FROM: your-email-address
RCPT TO: recipient-email-address
DATA - End of DATA section is punctuated with a single dot on it's own line.
Subject: E-mail-Subject
Text of e-mail goes here
. - The single dot
QUIT

SMTP return codes let the e-mail client know if all went well.

See: RFC 822 for more information.

Something about passwords and usernames flying around in plain text makes me shudder....
