[exim] case insensitive regex when using readfile?

Hi,

I added this last night to my setup:

  deny    condition     = ${if < {$message_size}{100k}{1}{0}}
          condition     = ${if exists {CFG_DIR/.DEFAULT/regex-blacklist}{1}{0}}
          regex         = ${readfile{CFG_DIR/.DEFAULT/regex-blacklist}}

Is there an easy way to make matching case-insensitive, without
having to diddle each line in the file?

Thanks,

Dave
