I'm leaning towards going back to the idea of disconnecting their systems from the network, and just connecting a clean PC, and seeing if the problem appears under those conditions.

Or just disconnect everything since he has his Linksys router in there now
and that should suffice for the local LAN side to take pings and such.

I think you've stumbled upon an interesting thing with the rogue connection to send e-mail. I wonder if there are other processes running, too.

Frankly, I'm running out of ideas, but if you can't unequivocally show that the problem is with Comcast, switching to DSL may just be a futile move.

Way too early for that I would think.

What happens late/early in the morning that could be a factor ? Cold,
humidity maybe ?

What time were these suspicious emails going out and what time do the
failures occur ? Why would data content bother a modem/router ?

Has any of the infrastructure been swapped out yet besides the modem/router
(wiring, ground block, splitter, etc) ? What are all the components currently
in the path to the pole ?

Etc.
