Hello Tonya,

not sure this applies to your case, but if you're applying outbound connections 
limits to a destination domain, and the destination MX manages multiple 
domains, you might in fact be opening more than 1 simultaneous concurrent 
connection to that MX.
You count 1 open connection from your MTA to virginmedia.com and 1 to 
ntlworld.com, but they are seeing 2 connections from your IP to their MXs.

Or, your MTA might in fact be exceeding configured limits during specific queue 

Both of the above are from direct experience.
