Mail error

Hi,

Doing some admin stuff today, I discovered that something isn't working
right with sendmail.

I have a virtualdomain (caba.org.ar) and webmaster is a virtualuser
pointing to notelodigo at advancedsl.com.ar (so webmaster at caba.org.ar ->
notelodigo at advancedsl.com.ar).  BTW infomail.infovia.com.ar is the MX
for advancedsl.com.ar and my server is the MX for caba.org.ar.

I've realized that all mail from this machine to that account gets
bounced. Here's an example:

# uptime |sendmail -v webmastera at caba.org.ar
webmastera at caba.org.ar... Connecting to infomail.infovia.com.ar. via
esmtp...
220 infoviaplus.net.ar ESMTP server (Tid InfoMail Exchanger v2.20)

/root/dead.letter... Saved message in /root/dead.letter
Closing connection to infomail.infovia.com.ar.
>>> QUIT
221 infoviaplus.net.ar closing connection 

That is from a COL 3.1.1 Server with a stock sendmail
(sendmail-8.11.6-8). If I run sendmail -v notelodigo at advancedsl.com.ar,
I get the same error.
I've also tried tha same from my home server (COL eServer 2.3.1) and it
worked.

The problem appears to be the "AUTH=root at monster.intrasoft.com.ar"
appended to the MAIL FROM by the COL 3.1.1 sendmail. In fact, I've
tried to send the mail manually (using telnet) and it worked:

[root at monster root]# telnet infomail.infovia.com.ar 25

So, is this my problem?? How do I stop sendmail sending that "AUTH..."
that's causin the delivery failure??
