[rt-users] RT3 RC4 auto create of non-privileged users fails

[Chris Hardie]

Hi.  I've got RT3 RC4 running on FreeBSD 4.7 with Postgres 7.2, using
qmail as the MTA.

Everything works fine so far except that when a non-existent user sends
e-mail to the e-mail gateway, a message is generated to RTOwner with
subject "Could not load a valid user" that says "RT could not load a valid
user, and RT's configuration does not allow for the creation of a new user
for your email."

I've poured through the mailing lists, documentation, and source code, and
can't seem to put together why this would be happening, so here I am.

Some relevant data points:

-RT writes a similar message out through syslog when the error occurs:

"RT could not load a valid user, and RT's configuration does not allow for
the creation of a new user for your email.
(/home/rt/lib/RT/Interface/Email.pm:483)"

-I can successfully open a ticket if I send the e-mail from an address
that belongs to a known privileged user.  So I know that e-mail ->
mailgate -> RT works in some capacity that results in database writes.

-The RT 3.0 draft manual mentions a config parameter
"$LookupSenderInExternalDatabase", but I can't find it referenced anywhere
else.  The other relevant documentation always implies that the
auto-creation of non-privileged users is turned on by default.  I've tried
setting it to 1 and 0, no luck with either.

-The .qmail file that I'm using looks like this:

| /var/qmail/bin/preline /home/rt/bin/rt-mailgate --queue 'tech support' --action correspond



Any help will be much appreciated!

Thanks,
Chris
