[exim] 4.93 Breaks MailScanner - Header File Change?

Hi,

Per page 493 of the current spec:

"Any of the above may have an extra hyphen prepended, to indicate the
the corresponding data is
untrusted."

The addition of extra hyphens on variables in the '-H' file breaks
MailScanner.  If the new behaviour is seen as important can it not at
least be made optional with a new configuration flag?

Thanks.

Regards,

Tony..
