That could be.  I usually use http://marc.info/?l=linux-kernel
or http://lkml.org .

I often post configs that are larger than that one.
I also checked my kernel mailbox and see several much larger emails, in
the 200KB/300KB range.

And the vger.kernel.org postmaster wrote on 13-AUG-2007:

"The posting limit is 400K for linux-kernel, netdev, and one
or two of the other lists."

so it could be something other than size that caused it to be dropped,
like html or some taboo word(s).  E.g., see
http://vger.kernel.org/majordomo-info.html#taboo

OK, I'll test that on a test machine.
