Yes I am. I have the quarantine of silent viruses turned off the the
quaranteen basically consists of encrypted zip files and other banned
attachments which didn't contain a virus.

How do you enable users to release their own messages?
Is it just a case if they have an account they can do a release or are there
extra priviledges or a setting which needs to be made somewhere?

I'll have a look at the code to mailwatch tomorrow. I might add a bit of
code to check to see if the user is an administrator and then allow them to
release the message. Or perhaps just look at the name of the virus and if it
is encrypted.zip then ignore the virus flag so it can be released.
