Thanks guys for the responses -- this really looks the way to go.

Does anyone know how sendmail distinguishes between:
 reject=451 4.1.8 Domain of sender address ................ does not resolve
 reject=553 5.1.8 .......... Domain of sender address .............. does not exist
It seems the former is to be interpreted as a 'temporary' condition while the latter
is to be interpreted as 'permanent' (and is by default deleted by fetchmail)?

Thanks
