X-LINK2STATE is used for Exchange bridgehead servers to notify each other
than the link state tables have been updated. I see these all the
time. Normally, I set up the SMTP Event *not* to write a log to the event
log just so that I don't have to look at them. I don't think there is alot
you can do about it- it is normal for your SMTP Filter to filter these out.
