You obviously missed the bit where I said that I'd whitelisted the /24 in
which tlug.jp resides because I *do* wish to receive TLUG traffic.

What for? They should be replying to the list unless an off-list reply is
specifically requested.

That's what I used to do until my server was getting hammered by dozens of
SMTP sessions per second, effectively becoming an ongoing DDoS attack.
Using the MTA to reject those connections was not something that was going
to scale and I was not about to start spending more money to get a better
server with more bandwith, more RAM and more horsepower.

You have absolutely every right to do that. Please do. Your server, your
rules. In the same way that it's my server, my rules.

Just remember that the most likely outcome of that is to get you removed
from TLUG because traffic from me will bounce back to the mailing list
software. Feel free to route my e-mails to /dev/null instead, though.

If you are a list official, or if a list official does ask me to
unsubscribe, then I will be happy to comply. Otherwise, I contend that it
isn't your call to say that I'm unwelcome here. Meanwhile, you may be
interested to know that I do happen to be a deputy TLUG moderator myself.
