Windows Server - Suddenly can't send large attachments.

Hello.

I have Microsoft Windows Server 2003 for Small Business Server
running service pack 2.
Intel Pentium D, 3 GHz, 2 GB Ram
25 mailboxes


Clients are mostly Vista Business with a few Windows XP Pro
Most are running Office 2007 and the rest Office 2003

Up until last Friday September 25 2009, all users could send emails
with attachments up to 20 MB in size.  Now they cannot.  I am not
exactly sure of the error message but will find out if necessary.  I
hope this is a no brainer.

Act 2010 premier has been installed two weeks ago but there were no
problems then.
We recently (yesterday) installed a Firebox Series E firewall but this
issue started before then.
Otherwise, no major changes.

Are there any Microsoft updates that would change this?  For the
server or the client?
Is there a group policy I should look for?
Is there a group policy I can modify to allow this?


I happen to know the server has not had updates for three weeks
because of our updating policies.
