Yeah, I've been in contact with Dave and he helped us by sending some
bounce emails to be investigated by TI's IT.  It seems that they have
worked around this problem, by whitelisting vger.kernel.org.  According
to IT, the problem was the way vger sends emails, by opening a single
SMTP connection to send loads of emails at once, instead of opening a
separate connection for each recipient.  The SPAM filters TI uses
consider that kind of behavior as SPAM by default.

Hopefully the bounces won't happen anymore with the whitelisting.  Dave
said he hasn't got any bounces for a while (he used to get 50-60 a day)
and that he will inform me in case he sees more bounces from ti.com.

I use my gmail account for these subscriptions, and have done it for a
few years, after having similar problems with my ex nokia.com email. ;)

As Kevin said, if you use ti.com emails and you get mysteriously
unsubscribed from some mailing lists, let us know.
