First, let me
say that I have not changed any settings in Exchange. There have been no
patches or updates. I have not changed any settings on my firewall. I have gone
through every setting and verified that they are still the same.
Everything has been running rather smoothly for
quite some time. As of some time this monday, things got rough. Very little
email from outside of our domain is actually getting through to the recipients.
Doing like a thousand test, I noticed that all emails greater than 200k aprox.
are not being processed by Exchange. It doesn't matter if it have an attachment
or not, simply if greater than 200k it won't go through. This only applies for
Incoming emails from the outside world and/or Mobile devices within my domain.
Everything works perfectly within my domain from Outlook to Outlook or OWA to
Outlook.
Greater than 200K
