I just discovered that the GroupWise IMAP server does not permit the 
target of a COPY command to be the selected mailbox.  GroupWise has other 
issues, but apparently nobody has ever complained about this.

Do other servers prohibit COPY to the selected mailbox?

Dovecot with mbox format doesn't allow it, because it caused it to  
crash and I never bothered to fix it. What's the point of doing that  
anyway?

Isode M-Box doesn't.
While this might not be very useful for end users, I am frequently using 
this for testing.

UW thought that it was important for some reason that I was never able to 
fathom.  The requirement to make that work is a primary reason why UW IMAP 
sucks so badly on Solaris and other SVR4 systems.

It doesn't matter with the new server that I wrote for MA (completely 
different filesystem technology), so it's mostly of academic interest to 
me now.

Right. The easiest/fastest way I know to put a million messages into a 
mailbox is to put a few there with append, then copy the mailbox to 
itself 10-20 times.
