I have one thing to add about this situation.  I'm using evo 3.8.5 and
have 12 pop accounts.  I have both a cable connection and a DSL
connection at my location.  I can simply change the cable between the
router and the modem, make one change in the router settings, and I am
connected to either the cable or DSL.

While connected to the DSL connection, everything works well.  However,
when connected to the cable, I get a notice that the connection has
timed out on random accounts.  That is, if I do a Send/Receive, one or
more accounts will time out.  Not  the same ones, different accounts
each time.  This leads me to think it is not in evolution, but in the
internet connection provided by the cable company.

One other thing that may or may not be related.  I cannot configure my
router remotely when it is connected to the cable, but can when
connected to the DSL.  This occurs on different routers so it is not in
my system.  My cable ISP insists they do not block any ports and,
obviously, my firewall is not involved as everything works while
connected to DSL.

This internet stuff is so much fun!

Bart
