BTW, see http://www.ietf.org/rfc/rfc3028.txt (RFC3028, "Sieve: A Mail  
Filtering Language") section 2.4.2.2:
    '[...]
    A header name never contains a colon.  The "From" header refers to a
    line beginning "From:" (or "From   :", etc.).  No header will match
    the string "From:" due to the trailing colon. [...]'

So Horde should make sure that either (1) the web interface rejects  
filters where custom header names contain the colon, or (2) the  
component that generates the Sieve script strips that colon.
