I will attempt that again. The last time I tried it...something threw me for a loop and I bailed - afraid that I would mess up something on my computer. Thanks for the advice on IMap....have been reading of big time problems with Mac users and Yahoo with the POP issue. Thanks!

Note the second line with POP and one further down with Mail forwarding...... This is for the US Yahoo email accounts.
