[CLUE-Tech] Mutt command-line question

[Dave Price]

Greetings,

I have a mutt CLI question.

I know that

'mutt -s "My Subject" recipient at domain.com < my_file.email'

Will create and send an email:
to = recipient at domain
subject = My Subject
with a body containing text from my_file.email

Question:

I would like to set an 'X-Header' field in the email also.

For example, If I want to set
X-Header:Priority = 2 (High)

Can I do this?  Where in the mutt command-line setup do I specify this,
or is it done from an .muttrc file?

- I know that I can use: '-F my_special_muttrc'
to get mutt to read a unique init

aloha,
dave
