Well, this time it's the first time an unsubscribe complaint contained
useful information, and I have no doubt that the user did his best to

*indeed* some mail servers delivering messages to us are *heavily*
blacklisted, and the change spam comes from them is high. We rely on
several combinations of triggers that must kick in before we block, in
order to avoid false positives.
However, that doesn't help people who want to unsubscribe and can't.
A web-interface won't help, as the key to mailinglist subscription and
also unsubscripiton is the double-opt in/out.
I.e. you must be sure that only those users who actually own the
email-address can subscribe or unsubscribe.
What would be helpful if we could provide a web interface that e-mails
them a URL they need to click, and if the magic token fits, they are
unsubscribed. Thus, they only need to be able to *receive* e-mail from
us (if they wouldn't, they had no problems of unsubscribing, as they
then won't receive mailing list posts :-)
Please forward such requests to the

with it but all people who can deal with it.
Maybe an interesting note: The postmaster@ account (and *not* info@) has
less filters, so if you send to this account, chances that mails arrive
are much higher, even if you would normally have been blocked.
So indeed his confirmation mail didn't reach the mailinglist system,
and hence he was not unsubscribed. But of course this is an error in
the mail-filtering/blacklisitng whatever. It definitely needs to be
Thanks for taking care of investigating! I will have a look these days.
In the meantime, ping postmaster@ (again, *only* this alias!) in case of
