Changing existing headers?

[Hippo Man]

I'm using contexts within mu4e, and I also know how to add custom headers via the `mu4e-header-info-custom' list.

What I'd like to do, however, is to alter existing headers when replying or composing within certain contexts. Here's one example: if I reply to a message that matches one of these special contexts, I'd like the "To:" header to be automatically changed to a different address, or to add additional addresses to the "To:" line.

Suppose the sender is sen...@example.com. For this example, if I reply to the message, I'd like the "To:" line to automatically be changed to ...

To: new...@example.com

... or even perhaps to ...

To: sen...@example.com, newu...@example.com, newu...@example.com

I might want to automatically change other existing headers, as well, such as "Subject:".

Is there any way to do this that is built into mu4e?

Thank you very much.

Hi,

You could set something up in the mu4e-compose-mode-hook, using the
various `message-add-header', `message-replace-header', etc. or any
general emacs text-processing function etc. functions.

See the section on 'Compose hooks' in the mu4e manual.

Cheers,
Dirk.

Thank you.

During the execution of `mu4e-compose-mode-hook', is the current context known? I'd like the header changes that I make via this hook to be dependent upon the context.

Yes - the function mu4e-context-current gives you the current context.

Thank you very much.
