We are running Exchange server 5.5, normally user using outlook 2000
or outlook express as email client, using auth SMTP and pop for email
services, working fine for 2 years. Currently some users report that
when they switch to outlook 2003 they got 553 header error sending
email to some domain, we suspect that this problem is related to OL
2003 not able to generate mail header as we test on OWA it works. Can
we change some setting in Exchange 5.5 to slove this problem.
many thanks
