Does the spam-messages attached with the spamcopper message?
For example when I've got 4 spams in my incoming folder in Thunderbird, I click on the report button and I get a new message called [Fwd:]
with 4 messages attached and the adress is submit.[xxxxxxxxxxxxxx][at]spam.spamcop.net
When I send the message I get quickly a response of errors from spamcop autoresponder.
I've got Thunderbird 1.5 (20051201)
To loafman: what is your number of version?
If everybody that has tried this extension could tell us how it works with his version of Thunderbird, it could be good to fix the problem.
I've send 2 e-mails to invisibill without any response.
Thanks for your help.
