We are running Ex5.5 SP4 on NT4 SP6
box. Our problem is that any internet
bound email with an attachment or which
includes a hyperlink wont process. All
other outbound mail seems to work fine.
After the email times out it is returned with
a “Host Unreachable”. Our firewall log
show that the Exchange box has
connected and then later has timed out
after the DATA command.
