you do not have permission to send to this recipient........Exchange server 2003 ent edition
Past few days when a particular user tries to send to few domains gets: email@example.com on date time you do not have permission to send to this recipient for assistance contact system admin <exchange2.domain.com #4.7.1 smtp;450 4.7.1 <exchange2.domain.com>: Helo command rejected: Host not found>
What is wrong and how to fix it. Is it my exchange server? I think mostly the domains I am having trouble are in India.
