HA!!! Yet another wonderful Yahho feature
I get that same thing from time to time.....it comes and goes.
I thought it was a feature to help relieve me of the task of answering my emails LOL
I set up my vacation response with a little disclaimer stating that Yahoo wouldn't always allow me to send email messages and that if somebody had an urgent need to contact me etc, that it was best to call OR at least leave me their number so I could call them.
And I thought AOL was a pain in the neck........
