Setting message priority levels

[John Niendorf]

I'm using Mutt 1.5.21 (Mutt patched from the Ubuntu repository) and 
connecting to the IMAP server that is run by my hosting company.

I was wondering is there a way to set the importance out outgoing messages 
in Mutt, like in Outlook (Yuck, I feel so dirty even typing the name ;-) ) 
or I believe also in Thunderbird?

Thank you,
