We have an Exchange 5.5 sp4 server on NT4.0 server sp6a.
My exchange mailbox has multiple email addresses. Quite suddenly, the main email address (reply-to) cannot receive email. No NDR’s are generated and the sender is unaware that the mail is undelivered. All other addresses in this mailbox can receive email. This behvaiour is repeated on all workstations in the domain if I log on as myself. All other users are OK.
What’s going on?
