Cool script. When I try it the smtp server chokes on the formatting of
the sender and recipient addresses.
I did:
( sleep 5 ; echo "HELO foo" ; sleep 5 ; echo -E "MAIL FROM:
<
kevin@isp.net>" ; sleep 5 ; echo -E "RCPT TO: <
kevin@isp.net>"; sleep 5
; echo "DATA" ; sleep 5 ; echo "Subject: foobar" ; echo ; echo "." ;
sleep 5 ; echo "QUIT" ) | telnet smtp.isp.net 25
>From a sniffer I can see it connect and pass HELO with a 250 (ok)
response from the SMTP server. However, the script then sends something
like "MAIL FROM: kevin\377\355\377...", which the server rejects with
"550 Sender address is invalid".
Is that ISO encoding or something? I tried escaping the '@' character
like this "MAIL FROM: <kevin\@isp.com>" with no luck. I also tried echo
-e and echo -E.
If I telnet to port 25 on the SMTP server and type all this by hand it
works perfectly.
Hmmm, seen this before?
