[rt-users] Mailgate not working: Could not record email: Could not load a valid user

[Tek Bahadur Limbu]

Dear all,

I am very new to RT and just setup RT 4.2.6 on a Centos 6 VM machine which
has an old copy of Qmail running. Installation went fine and now I can
create Tickets and Reply to Tickets via the Web interface at:
http://my.company.com/rt/.

However, I am having problems while trying to create Tickets via Email.

While sending email via Mailgate using the command below:

(echo from: rt at gmail.com  Subject: test; echo; echo test) |
/opt/rt/bin/rt-mailgate --queue General --action correspond --url
http://my.company.com/rt --debug

I see the following errors on the screen:

/opt/rt/bin/rt-mailgate: temp file is '/tmp/yBDiQmLWn3/D5Z8PB7NBF'
/opt/rt/bin/rt-mailgate: connecting to
http://my.company.com/rt/REST/1.0/NoAuth/mail-gateway
not ok - Could not load a valid user

In the rt.log, I see the following:

 [Wed Aug  6 07:27:53 2014] [debug]: Encode::Guess guessed encoding: ascii

[Wed Aug  6 07:27:53 2014] [error]: Could not record email: Could not load
a valid user (/opt/rt/share/html/REST/1.0/NoAuth/mail-gateway:75)

I did some searches for this error which says there is some
mis-configuration in the Apache settings or not providing rights for
Everybody in the General Queue to create and reply to Tickets. I have tried
the help and solutions listed but still facing the same problem.

I have also granted both Create and Reply rights to Everybody and
Unprivileged for the General Queue.
Regarding the Apache Web config, I have the following:

AddDefaultCharset UTF-8
Alias /rt/NoAuth/images /opt/rt/share/html/NoAuth/images/
ScriptAlias /rt /opt/rt/sbin/rt-server.fcgi/

DocumentRoot "/opt/rt/share/html"
<location /rt>
Order allow,deny
Allow from all
Options +ExecCGI
AddHandler fcgid-script fcgi
</Location>


Regarding my RT_SiteConfig.pm configuration, it is listed as below:

Set( $rtname, 'my.company.com');
Set($WebPath, "/rt");
1;

Set(@ReferrerWhitelist, qw(www.example.com:443  1.2.3.4:80 my.company.com:80
));
Set($Organization, "my.company.com");
Set($WebBaseURL, "http://my.company.com");
Set($WebDomain, 'my.company.com');
Set($CorrespondAddress, 'correspond at my.company.com');
Set($CommentAddress, 'comment at my.company.com');
Set($OwnerEmail, "admin at my.company.com");

Set($LogToSyslog    , 'info');
Set($LogToFile , 'debug'); #debug is very noisy
Set($LogDir, '/opt/rt/var/log');
Set($LogToFileNamed , "rt.log");    #log to rt.log

Set($WebRemoteUserAuth , 0);
Set($WebFallbackToRTLogin , 1);
Set($SenderMustExistInExternalDatabase , 0);
Set($AutoCreateNonExternalUsers , 1);


What could be the problem here?
Any help will be very much appreciated.


Thanks,
Best Regards,
