Troubling sending mail to some smtp server [Sendmail]

I have a problem sending msg to account of fastwebnet.it.
I always recive a message refused.

Making test via a telnet connection I made this discover.

If I close the message WITHOUT put the command Subject at the end of
the msg, it's refused

This behavior could be caused by some sendmail setting ? If true how
can change to work correctly ? If not could be caused by some client
configuration ?

Thanks to all for any kind of help

Are you getting that log from a manual telnet? Coz you're getting
syntax errors from not correctly formatting the "MAIL FROM" and "RCPT
TO" commands, and I'm pretty sure a sendmail on your end wouldn't make
those kinds of mistakes.

Yes I know it, but when I use the right command for mail from or rcpt
to I still get error and the end if I don't close message with subject
command. Any suggestion ?

thanks for your attention

best regards

If you send a normal message, via a normal mail agent (e.g., mailx,
or, search google for a very useful Perl script called "sendEmail") --

and that message contains a "Subject" line --

does it complain?

Vs. -- if you use the mail agent without a subject -- ??

It occurs to me that the SMTP server on the other end is simply doing
some validation on the headers in the message (the message body being
the part after the "DATA" command). I think sendmail doesn't normally
do that with the message body, but looking again over your transaction
logs, I don't think your destination server is using sendmail.
Generally, sendmail will announce itself and its version number at the
first connection.

E.g., if you "telnet sendmail.org 25", their sendmail server responds:

220 services.sendmail.org ESMTP Sendmail 8.14.0.Alpha1/8.14.0.Alpha1;
Mon, 26 Feb 2007 17:03:55 -0800 (PST)

So, right away you know they're using sendmail (as well as they
should, since it's their product!) and they're using version 8.14.0.

Looking once again at your logs:

220 aa022msr.fastwebnet.it ESMTP Service (7.3.105.6) Ready

So -- not sendmail.

I am unfamiliar with whatever smtp program is being used at that end,
but whatever it is, THAT is the guy complaining about your input and
giving error messages. Possibly it's an anti-spam measure to
guarantee that messages are at least correctly formatted.

I.e., this is not a sendmail problem.

Sorry. <:-(
