"Release and whitelist" not working today

Hope somebody is still reading this...

Just tried to "release and whitelist" an item of goodmail from my 
Spamcop account, and it didn't work!

Got the usual "message has been released" message on my screen, but the 
message was still sitting in my Spamcop webmail account. Tried a second 
time, and a third time - same result. Checked the mailbox to which mail 
gets forwarded from my Spamcop account (to see if maybe the message had 
been forwarded without being deleted from my Spamcop account), but so 
far it hasn't arrived there.

Something clearly not working as it should!
