single quote in mailbox

[Patrick Welche]

As ever, I'm moving users from courier to cyrus. All was well until I hit
a mailbox with a single quote in its name which cyrus rejects. I had a look
at rfc3501 and as far as I can tell, it doesn't prohibit a ' (allows astring).

imap/mboxname.c allows:

#define GOODCHARS " +,-.0123456789:=@ABCDEFGHIJKLMNOPQRSTUVWXYZ_abcdefghijklmnopqrstuvwxyz~" 

So, is there a reason for not allowing ', or is it a simple ;) matter of adding
it to GOODCHARS and wondering about all the places in the C code which need
\' ?

Cheers,

Patrick
