automatically deleting messages

[Seb]

Hi,

I'd like to just delete incoming messages from a particular address and
this part of the manual seems relevant:


,-----[ (info "(gnus)Fancy Mail Splitting") lines: 5019 - 5022 ]
| `junk'
|      If the split is the symbol `junk', then don't save (i.e., delete)
|      this message.  Use with extreme caution.
`-----


I'm not sure I understand how to use it, so does someone have a working
example?  Thanks.



Cheers,
