[exim] rejecting addresses with colon in the local_part - po…

Hi all...

Basically, I want to reject local parts with the colon character (:)

deny    message       = Restricted characters in address
        local_parts   = ^.*[@%!'"\\s,:]

Something like the above... I escaped, used \N and tried quite a few
variations but none of them seem to work...

Exim seems to think the colon is a separator, like in the case below:

  deny    message       = Restricted characters in address
          local_parts   = ^[./|] : ^.*[@%!'"\\s,] : ^.*/\\.\\./

Thanks,
g.
