Can I use my_hdr from a macro?

[Chris Green]

I want to create a macro in 'compose' which does something like the following:-

Set From: to something special
Send the message
Set From: back to the default

I can't quite see how to do this, how can one use my_hdr from a macro?
my_hdr isn't a function is it? ... or is it possible to just say
<my_hdr> in the macro definition?


Alternatively (but still needing a macro) I could do something that
works in index and pager and is a 'special' reply:-

Set From: to special address
<reply>
Set From: back to default


So the question is basically how do I set my From: address in a macro?
