Environment: Exchange 2010 SP3UR5, two AD sites with split roles all over the
place
So.. I inherited a pretty solid environment minus the Receive connector we are
using for SMTP Relay. Within the Remote IP Ranges (allowed to relay) there are
a TON of addresses, and yesterday we ran into an issue where we would add an
address and three minutes later it would drop. Knowing the attribute has some
type of rangeUpper assigned to it, I thought we hit the maximum so I
consolidated the list down a bit and pow, it worked.
Now, I guess the question is what is the maximum number of IP addresses that
can go into the attribute ms-Exchange-Smtp-Receive-Remote-IP-Ranges? If I look
at the attribute both in Production and Lab (Lab is fully up to date) it shows
the same rangeUpper as 200, but I know this is impossible since we have to have
at least 500+ IP addresses that relay off Exchange. I can pull a list later to
confirm.
Any ideas? I am stumped, as I know this is a limitation due to the rangeUpper
but that value doesn't make much sense.
Thanks!
