Maybe he encountered the same problem I am encountering right now.

I subscribed to the OOo users list from my work email address. We use an
outsourced anti-spam service (webroot), and use their system for our
outbound relay host. Well, webroot uses what is called BATV address
tagging, to minimize/eliminate backscatter problems - and it works very
well for this:

http://en.wikipedia.org/wiki/Bounce_Address_Tag_Validation

Yes, the RFC is expired, but that is irrelevant - a LOT of people are
starting to use it, or something similar.

What this does is adds a unique tag to the envelope sender address, so
that instead of a simple email address:

[email protected]

it looks like this:

prvs=2588cf9233=local=example.com

I am subscribed to literally dozens of lists with this address right
now, and have been subscribed to hundreds using this address in the past
3 years we have been using them, and only encountered this kind of
problem once a long time ago on some obscure list that I can't even
remember what it was.

The problem is, the OOo list software is ezmlm, which is brain-dead when
it comes to BATV address tagging, and now I CANNOT UNSUBSCRIBE MYSELF.

I assure you, I am *very* experienced with this kind of thing, so I know
I am trying to unsub using the proper procedure. The problem is, the
only method the OOo lists provide for unsubscribing is via email, and
since every time I send an email from my work address, it has a
different BATV tag, the unsub process fails - and since either ezmlm
doesn't have a user web interface that would let me do this myself (like
Mailman does), or the OOo list moms haven't enabled it, so I cannot do
it through the web.

The correct solution is for either ezmlm to be patched to accommodate
BATV address tagging (we are NOT the only ones using it I assure you),
or the OOo list moms should switch to a list manager that can handle it
- like Mailman.

I've seen how much backscatter this blocks, so I assure you, I wouldn't
ask webroot to disable this feature even if they would, which I doubt.
