Is it possible to use send-hook to 'edit' a header

[ಚಿರಾಗ್ ನಟರಾಜ್]

For a more generic solution that I just setup in my config file:

1. Use the following send-hook: send-hook ~l "set from='Name <first.name at my.domain>'"
2. Declare all of the mailing lists to be caught by the ~l parameter using lists: lists mutt-users at mutt.org gnupg-users at gnupg.org

Now, whenever I reply to a mailing list, my From address is set using the send-hook. Of course, this is only desirable if, in fact, you want the same hook run for all mailing lists (my case). Otherwise, you can use my previous solution, which uses the ~t<pattern> limiter to specify the pattern of To addresses that the send-hook should be run on.

Also, running this based on the To header (rather than the From header) is better because if you use the list-reply function (bound to L in the index by default), then you _know_ what the To address will be (the mailing address of the list) (remember, this is the To address of the email you're _sending_). The slight downside is that you might need a from-address-based pattern if you regularly reply to individuals who sent the email (rather than sending the email to the mailing list), since this type of pattern won't catch that. In that case, simply change it to ~f<pattern>, but keep in mind that it's the From address _of the email you're sending_, *not* of the received email (the one you're replying to).

HTH!
