I wasn't aware of the editor issue.  Does that mean he is using 
someone else's code ?   I would tend to agreed with you otherwise.

Hangs head in shame...... Never used pine.  Sorry.

Kmail lets you choose what items you want to delete from the server 
based on message size.  For instance I have a set maximum size of 
25K.  Any mail with a size greater than this can to be selectively 
kept or deleted by choosing one of three options.  "Download, leave, 
Delete" on a per mail basis.  It works very well and doesn't cause 
any issues.

All mail under this size gets downloaded and filtered by "Mail Filter"  
Anything marked as spam goes straight into the trash can (Wastebin) 
the rest get placed into the appropriate mail folder for further 
attention at my leasure.
