Do I need idled on or not?

[Murray Trainer]

Hi All,

I noticed the line in cyrus.conf below which was commented previously
and now included in SuSE 10.0:

# this is only necessary if using idled for IMAP IDLE
idled         cmd="idled"

The IMAP IDLE feature sounds like a good idea - do any mail clients
support it yet.  If so I will probably leave it on.  Does this mean I
can tell my e-mail clients using IMAP not to check for new mail?

Thanks

Murray
