    Oops , I am sorry , If I sounded like a spammer. But What I actually
    want to do is find out the recipients in a email in a milter program (
    from the headers , and not from rcpt callback ) . This milter plugs in
    to the SMTP server , ie sendmail and now I can do a whole lot of
    validation and email redirection depending on the headers, which is the
    real requirement.

    There is actually a perl module for milter Sendmail::Milter, But it
    uses some untested thread functions and simply hangs most unpredictably
    ( I am using perl5.6.1 with threads on redhat 7.2) . Also A milter in
    perl is inherently very slow as compared to one in C.

    So I translated most of code into C and this script runs very well.
    But I miss my favorite regex's in C

    BTW , I cant see any reason Why a spammer would insist on using C
    against perl for his database

    Thanks
    Ram
