I've not had trouble sending mail, but if you think the MTU is
your problem, you should start by setting the MTU on all machines
to 1492 if your ISP uses PPPoE.  If that doesn't help, or you want
to do more detailed diagnostics, head over to broadbandreports.com
and use their tweak test to check your Windows machines.  Make
sure that if you do change the MTU than you set the MTU to the
same value on every machine on your network.
