Can someone please fix the mailing list software?
This has been
reported every once in a while by a bunch of people for over ten
years.
Bounces aren't caused by the mailing list, they're caused by the
destination mail server.

I agree. Seems like it's fixable:

Looks like you can play with the bounce score threshold and bounce score
reset interval.
Wonder what the default is?

The best thing to do is analyze the logs and calculate the best intervals,
adjust to suit. You can change for example to stretch each bounce to take
longer each time. There are also ways to turn off bouncing selectively, or
respond dynamically based on how the receiving end reacts to the bounce. I
have found watching for a few days works.

Depends on how you view `cause'.
My own mailserver is one what I believe must be a very few that will
reject mail for, for exmaple, being marked as containing 8859-1 text
but including octets like 0x92 which do not occur in 8859-1 text. Yet
such bounces are actually caused by the composing MUA's nonconformance,
with every intermediate mailhost that handled the mail complicit by
acquiescence; my mailserver causes the bounce only in the immediate
sense of being the one that blows the whistle and throws down the red
flag, the one that flags the offence for what it is.
What I've been wondering for a while is the span
of time over which
the bounces are counted.
I haven't read the code for that logic in any mailing list manager (or
at least if I have I don't recall). But...
I can understand shutting a subscriber off for getting
10 bounces in
as many minutes. On the other hand if those 10 bounces are spread
over two months, it seems rather severe.
It depends. If those 10 bounces in as many minutes were for 10
consecutive messages, perhaps. If they were for 10 messages mixed
randomly among 250 others that were delivered fine, it seems somewhat
excessive to me.
If I were writing such code, I would pay attention to not only count
and time but also to non-bounced list traffic.
