Sending Mail From Command Line Using TelNet

The following explains how to send an e-mail form the command line using TelNet. This procedure has been tried successfully with HOTMAIL on a SUSE 9.2 machine a few years ago.Recently it has been re-checked on debian lenny with bezeqint mail server.

1. First you need to find the encoding of you user name in base64. In my case the encoding of :
   bknpk@hotmail.com is YmtucGtAaG90bWFpbC5jb20=.
   
2. In a similar way you need to find your password encoding. The script sends the first input parameter and puts in the subject and in the mail content of your message.
3. The script can be seen at - Perl Script
4. An example of how to call it from a PERL script- Call From Perl Script
5. I use hotmail and you need to get the right daemons set. hotwayd/hotsmtpd are POP3/SMTP-HTTPMail gateway daemons.
6. The HTTPMail protocol is used by the mail servers Hotmail, Lycos, Spray and MSN.
7. Recently my TELNET script fails. I believe because it does not support encryption. Therefor I use:mailsend


8. Some mail serevers use SSL. I have discovered, that hotmail stopped working with my telnet script and gave the following error message after I tried to authenticate:
   530 5.7.0 Must issue a STARTTLS command first
   


9. So I needed to re-write my script. This time I used openssl command
   openssl s_client -starttls smtp -crlf -connect mail.bezeqint.net:25




10. Please note that spamming is not allowed. This send mail script is only to allow me getting message on assorted linux machines at home to work, when their status changes. I modified the script accordingly: script to send a mail openssl script.


11. A few notes
    You have to modify the script and put your own user name and passworded encoded to base64.
    Also be aware that I created a special new account for this purposes, but hotmail did allow me to send mail. I could only do it from my old account. So they might have a restriction on new accounts, which I intend to check.
    The script was tried on a debiam lenny machine.

I would be happy to offer my services. Call ASAP !
