CFMAIL abused by spammers - Coldfusion - Advanced Techniques

Since a couple of weeks, a mailform of me is abused by a spammer. I receive 5 mails of which one has a changed header and strange code. I want to use the IsValid function, but is it enough? Can I prevent that spammers put TO: CC: or FROM: code in one of the fields of my form? My mails are automatically written in an Access database. Can I use the database to prevent that spammers put malicious code in it? I notice that more users have the same problem, but I didn't found a good solution to keep spammers ...

    Default CFMAIL abused by spammers

    Since a couple of weeks, a mailform of me is abused by a spammer. I receive 5
    mails of which one has a changed header and strange code. I want to use the
    IsValid function, but is it enough? Can I prevent that spammers put TO: CC: or
    FROM: code in one of the fields of my form? My mails are automatically written
    in an Access database. Can I use the database to prevent that spammers put
    malicious code in it? I notice that more users have the same problem, but I
    didn't found a good solution to keep spammers away from my mail function.
    Thanks for your help.

    Use IsValid on any form field that allows an email address entry ... it's these
    fields that get used in the CFMAIL tag directly and the ones you need to check

    The IsValid will help get rid if the injection methods.
