IDLE and idle

[Arnt Gulbrandsen <arnt@xxxxxxxx>]

Hi,

RFC 3501 section 5.3 permits a server to send untagged unsolicited 
EXISTS responses to a client even when it's not processing any command, 
under certain circumstances.

I'm not familiar with any servers that do this. (UW sends OK, but my 
question is about EXISTS.) Are there any that send EXISTS, and if so, 
which?
