This might be what you want:
http://cgi.silverstones.com/library.php#spamcop_submission

You could have reached that by yourself by picking from the menu:
Help -> FAQ -> Macro, filter and template library -> and browse along
It's a real treasure house that one.

Upon trying to implement the filter at http://cgi.silverstones.com/library.php#spamcop_submission I I cannot work out out to install it.
I use The Bat 3.80. The filter info advises to install the filter into the sorting office by pasting it with Ctrl V. I cannot see how to do that with this version so I am presuming the instructions are for a previous version.
For others info the filter specified is:

BeginFilter
Name: Submit spam to SpamCop
Active: 0
Source: \Inbox
Target: \Trash
CopyFolder: \\\\none
MainSet: 40.
Actions: faMarkRead,faNewMsg,faExport,faoExportOver,faoExportKludges,faoManualOnly,faoHotKey,faoSaveUnix
NewAddr: submit.spam@spamcop.net
NewTemplate: %put\3D\27C:\5Ctemp\5Cexport.txt\27\D\A
ExtFile: C:\temp\export.txt
HotKey: 49235
SaveTemplate: \D\A
EndFilter

Can anyone advise how I would put this filter into ver 3.8?

Thanks

Thanks for that info.
For anyone else reading this thread you will need to prefix the filter with "$$$$ TB! Message Filter $$$$" before you copy it otherwise the bat does not accept it as a filter that can be pasted. So the entire thing that you would copy and paste would be

$$$$ TB! Message Filter $$$$
