Hi, Jasen -
Doh! Many thanks for the confirmation… I'd actually read that paragraph
twice yesterday and still failed to make the connection.
For those interested, I think for the time being I'm going to apply
cutthrough only to messages arriving from the Big Bad World and skip ones
emanating from on-site SMTP servers. (I had reasons for trying to do it:
don't ask! :-)
Many thanks,
Mike B-)
