MSExchangeTransport 5015 and 5016

Getting these messages in the event log after I removed the RGC while completing my migration from 2003 to 210.

One of the connectors it references is the "Internet Mail" connector while I can still see and the other is an old connector that has not existed for many years from an old phone Octel phone system. I found them in ADSI edit and the "Internet Mail" connector shows up still in 2010 in the HT | send connetors section. can I just disable or remove that one and delete the Octel connector via ADSI Edit?

Our mailflow seems uneffected, I tested it and watched the queue's ... don't see anything indicating that there is any kind of queue backup or flow issues.

but I know how touchy this thing can be so I was wondering if anyone else out there has run into something similar to this and can shed some light on it. I have worked too hard on this to just start guessing. =)

thanks!
