Is there just one HT?
Sounds like you are being bitten either by the transport dumpster or by
something huge trying to come into your HT. You do have limits set on the
connectors, right? (And I mean on the CONNECTORS, not at the global level or
per-user level.)

We had 2 servers running HT during migration, and went down to 1 about 2
weeks ago, but only had 1 before forever. I did see that the HT had an
unlimited send/recv size although we have a max size on smtp and the spam
filter so I fixed that.
I turned the server we migrated away from which was
You just got hit by an attempted DOS. :)
You should be able to look at your connection logs (on by default) and see
where the emails were coming from.
This is also why setting ALL the send/recv limits is important.

Hi all,
Does anyone have any recommendations for which port(s) to test on an Exchange
2010 CAS server for load-balancing / operational status?
We're currently using 135 but stopping the RPC Client Access Service -
effectively killing the server - doesn't close port 135.
SP1 if it matters.
135 is the RPC port mapper. It's used to negotiate an rpc connection for a
specific service, and that can be any arbitrary unused port above 49152.
If you want to lock down the ports on the firewall, you'll need to edit the
registry to force the CAS servers to only use specific ports:
That's actually what I've done. RPC is set to use a static port and we monitor
that.

I'm setting up a spam appliance that needs to talk to AD for recipient
verification and login authentication.
So far, the only user name that I've been able to connect with is
administrator. Is there a built in user account that has the right permissions
short of administrator? On the other

Anyway, it's all about WHAT on the CAS you think are the services to monitor.
In general, you should look at ports 80 and 443 and you can build synthetic
transactions for them for testing
All user accounts have the necessary access, assuming it's only doing inquiries.
You PROBABLY need to use either the UPN or the DOMAIN\USERNAME syntax to
connect. Some really stupid appliances require you to specify the entire
distinguishedName to the user object. For example

Thanks to others for replies, too.

Looks like connectivity logs are not on, using this cheat sheet:

I went to the transportroles\logs and there isn't even a connectivity
