[Dovecot] DON'T DELETE THIS MESSAGE?

[Knute Johnson]

I have a new install of FC5 running dovecot 1.0.0 beta 2.7.  I get my 
mail with POP3 but I have a user using IMAP.  They both work great 
but I keep getting a message from dovecot in my mail saying DON'T 
DELETE THIS MESSAGE -- FOLDER INTERNAL DATA.  I think it is there to 
help keep track of IMAP messages.  Since I use POP3 is there any way 
not to have it show up all the time?  I've deleted it, I've deleted 
my account and re-added it but it keeps coming back.  Dovecot is also 
making a 'mail' directory in my ~ that I don't think I need.  What 
can I do about this?

Thanks,
