I'm using contexts within mu4e, and I 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 sender@domain.com. If I reply to the message, I'd like the To:
line to automatically be changed to:
To: newuser@domain.com
... or even perhaps to ...
To: sender@domain.com, newuser1@domain.com, newuser2@domain.com
I might want to automatically change other existing headers, as well, such as Subject:
.
Is there any way to do this in mu4e?
