That's not possible is it? I wanted to use the same feature
(mailfrom=) in sender verification to use something else then the
bounce user in de 'mail from', but this option only seems to be
available in 'header_sender' when checking senders ..
Why? ... (why can't it be used for 'verify = sender/
callout=mailfrom=blabla....' )
Yours,
Chris
