I don´t know what changed, but to send a email using telnet line command you need a trick with 6.5.2 server.
telnet IP_SERVER 25
HELO FRIEND
MAIL FROM:“ANY-EMAIL”
RCPT TO:“ANY-EMAIL”
DATA
SUBJECT:“ANYTHING”
(PRESS ENTER HERE)
“NOW YOU WRITE YOUR BODY MESSAGE”
.
If you don´t press enter after subject line, your body will not appear.
Regards,
GC
Subject: telnet port 25
See RFC2822. There must be a blank line between the headers and the message body. If it once worked without a blank line, that was a bug that has now been fixed.
Subject: RE: telnet port 25
Thank you !
Subject: telnet port 25 – same problem exists in 6.5/6.5.1
Good post GC but this has been the way in R6 world – if there is not the enter key pressed after the subject line in R6.5 and R6.5.1 the same behavior is repeated as well.
