Are you certain this is the fault of Cyrus and not a deficient client
that happened to work with UW?  Are they all using the same kind of
phone (what phone)?

I'm pretty certain such headers are coming from your MTA (postfix) and
not Cyrus.  But I've never used Cyrus with procmail as SIEVE is usually
sufficient.
