Can SIEVE scripts filter based on the body of an email message?

Posted on 2004-11-02

I am new to SIEVE scripts and am running a Kerio MailServer which utilizes them.  I am impressed with the capabilities, however, I have not been able to get a straight answer on whether you can filter the message rules based on the message body.  I have several users who wish to sort their mail according to content that is only differentiated based on the message body content.  Please point me in the direction of where I can get the answer to this question (RFC?) and if it can be done, what the syntax is.

    Have a look at but I don't know if body is supported by the Kerio Mail implementation

    The rfc for the sieve-language can be found here:

    Thanks for the info...I am still awaiting word from Kerio on their implementation.  Appreciate seeing the example though...I scoured the web and could find nothing supporting my cause.
