[NTLK] Receiving NewtonTalk messages... Gmail issue?

[Andrei Chichak]

The RTEMS RTOS group uses this same email distribution system, so I asked their support guy (me not knowing what I’m talking about wrt mail) and he suggested that Google will reject mail that does not have the

X-List-Administrivia

header filled in. 
I noticed that the message that I received from Dennis Swaney did not have that field in the headers.

Just a thought.
