Hi Ben Spead,

You can set priority by adding additional headers such as X-Priority and others. e.g:
 

 do msg.Headers.SetAt(1,"X-Priority")
 do msg.Headers.SetAt("High","X-MSMail-Priority")
 do msg.Headers.SetAt("High","Importance")

Thanks

Yes you can use functions like Contains() or SubString().
