Weird "too many hops" issue

[Rob Morin]

Hello all...

I have recently been experiencing lots of "too many hops" on my mail server..

Redhat 8.0
Sendmail 8.12.10
Mailscanner 4.28.6
McaFee (uvscan)

The funny thing is I turned off Mailscanner, I mean just used plain old sendmail, and I got none of these loops/hops. As soon as I turned it on again it started right away..... I will provide  some log stuff below.....

What else should I do to test or what should I look for?

Thanks for any help...

Times mailscanner was turned off then on again.....
