Well what a load of tosh this is!! Thankfully no-one replied to it -
probably stunned by my stupidity :-) First of all the subject should have
been 'headers_sender_verify' and not the syntax check. Secondly, our reject
log was showing that the 'Resent-' headers were being rewritten where
appropriate. I just wasn't seeing it - "couldn't see the wood for the trees"
as they say.

Apologies,
