||Note: The following technique does not work with Poco's built in junk mail filtering, there is another article that explains how to do this.
Download the "MarkAsRead" script from the Poco registered users area and run that
script in your filter (using the Run Script command). This must be done before moving the
message to the trash. BTW: For pre Poco 2.61 the "Trash" mailbox will still be coloured with the new mail colour, I
don't know of a way of removing the colour from a single mailbox without affecting the colour added
to other mailboxes during the download.
