My problem was that both my smart(alec) phone and my regular
mail are using the same account but with different aliases. I have
worked out a way to send from both sources using the same alias,
by going to the web facility associated with my account, and changing
the ailing alias to the same as the one for the smartmouth .. er ...phone.
 
It's a wee bit of a work around but it works around.
 
Thanks to Peter (D.) for an inventive thought.
 
Cheers,
Peter (M).
