User 'xxxx@someother_domain.com' could not be loaded in the mail gateway

All,

I am having a problem where many of my users can not create tickets via email.     In the log file, I see:  User  'xxxx@someother_domain.com' could not be loaded in the mail gateway.    All of these users have different email domains then the home office (mydomain.com) does, and I wonder if that is the source of the problem?

The only relevent setting I see is Set($Organization, ‘mydomain.com’);

My users authorize via ldap, but, that seems to be working fine.   I have checked their email addresses in the ldap db, and they match what they are sending as.

Any ideas?

Thanks
Scott
