Hi All,
      I am using evolution 1.4 on a Mandrake 9.2 system.  Some of the time I
am connected via ethernet but at other times via a 802.11b net to a
128Kbps adsl link (at home).

When on the wlan/adsl connection evolution frequently hangs with
"pinging IMAP server ....." in the status line.  This seems to take at
least 10 minutes to time out.

pretty standard for network apps... 

Running standard pings over the link I get about a 3% Packet loss -- I
will be taking this up with the supplier.

Quite why evolution thinks it is necessary to ping the server and why it
hangs up with such a long timeout is beyond my comprehension.

it doesn't ping the server, it sends a IMAP NOOP command which is
supposed to prevent the server from closing the connection (lets the
server know we are still there). It also tells us of updates.

Does anyone else have this trouble? Is there a way to shorten the
timeout on (or preferably disable) the pings.

nope and nope. well, you can press the Stop button in the toolbar - that
should force a disconnect (there's a few code paths where that doesn't
work, but for the most part it should)

Some times other operations (particularly those that have sub ops like expunge) fail.

sounds like your network is flaky and/or your imap server :-(

I have seen this problem very occasionally while connected via ethernet and
somewhat more frequently while on a dialup connection -- but nothing
like as frequently as with the dsl link.
