## 3.12. User defined headers

Usage:
`my_hdr` string
`unmy_hdr` field [ field ... ]

The ``my_hdr'' command allows you to create your own header fields which will be added to every message you send.

For example, if you would like to add an ``Organization:'' header field to all of your outgoing messages, you can put the command

> my_hdr Organization: A Really Big Company, Anytown, USA

in your `.muttrc`.

Note: space characters are not allowed between the keyword and the colon (``:''). The standard for electronic mail (RFC822) says that space is illegal there, so Mutt enforces the rule.

If you would like to add a header field to a single message, you should either set the edit_headers variable, or use the edit-headers function (default: ``E'') in the send-menu so that you can edit the header of your message along with the body.

To remove user defined header fields, use the ``unmy_hdr'' command. You may specify an asterisk (``*'') to remove all header fields, or the fields to remove. For example, to remove all ``To'' and ``Cc'' header fields, you could use:

> unmy_hdr to cc
