send mail error

Hi,

When i send mail to an user, in a domain,
i received a message in mail.log:

Feb 15 13:31:02 mastermm sendmail[9025]: j1FGV2D09025: from=root, size=715, class=0, nrcpts=1, msgid=<200502151631.j1FGV2D090
25@mastermm.globosat.net.br>, relay=root@localhost
Feb 15 13:32:18 mastermm sendmail[9027]: j1FGV2D09025: to=username@globosat.net.br, ctladdr=root (0/3), delay=00:01:16, xdelay=
00:01:16, mailer=esmtp, pri=120715, relay=globosat.net.br. [10.2.1.54], dsn=4.0.0, stat=Deferred: Connection reset by globosa
t.net.br.

The DNS is configured right.

I don't change the aliases file.

Wait

Fernando.

"Deferred" suggests that the mailserver for that domain is not accepting mail at the moment.
Try this as a test:
From any server with an outside internet connection, type:

telnet mastermm.globosat.net.br 25

This should establish a "raw" smtp connection. If it doesn't throw you right out at this point, type:

ehlo

This tells it you want to use Extended SMTP protocol, (esmtp, which they use), and may give you a little extra info. If it still hasn't thrown you out, type:

help

and read what it says. They may reject mail with attachments, or over a certain size.
If it still hasn't thrown you out, type:

quit

to drop the connection. In that case, try sending your mail again. If it still fails, the problem is probably at your end.

If you want to know more about SMTP/ESMTP protocol, check out this link:
http://www.cse.ohio-state.edu/cgi-bin/rfc/rfc2821.html

But I'm afraid it can't help you to configure sendmail (and neither can I: I helped to develop an email gateway many years ago, and I used to type raw SMTP commands during testing)
