Thanks Wayne, will set up a new Portable install this weekend just for
testing Maildir on some of my less important accounts...

I'm unconcerned about having to fix any local problems.

What I'm mostly worried about is something weird that actually causes
data loss on the server side.

So, before I do:

Has anyone ever encountered, or are there any Maildir related bugs -
'fixed' or otherwise - reporting data loss on the server side?

Thanks again...
