This is the default untrusted user Debian uses for Apache and packages that 
run under Apache.

I think so.  However I'm running exim here and can't help you directly with 
sendmail.  

Perhaps your sendmail logs or /var/log/deamon.log on Debian will give you a 
clue as to what's happening.  I would assume that sendmail is rewriting that 
From: header because some rule is set requiring it to use the real 
username/hostname of the process sending mail though it.   And since RT runs 
under the www-data user, that makes some sort of odd sense to my late-night 
brain...

From /usr/share/doc/rt3-clients/README.Debian :

If you are using Sendmail you will need to add rt-mailgate into the
/etc/mail/smrsh/ directory. Do something like:

ln -s /usr/bin/rt-mailgate /etc/mail/smrsh/rt-mailgate

The smrsh directory contains all the binaries that Sendmail is
permitted to run via the '|program' syntax in order to improve the
over all security of your system. See smrsh(8) for more details.

Although I assume if you're opening tickets okay via e-mail this isn't the 
problem.
