hooks and mail

hooks and mail

[Guldo K]

Hello.
I'm sorry, but I can't understand how do hooks work.
I'd like to set reply-to to a certain value;
I wrote:
(add-hook 'vm-mail-hook
  '(lambda()
    (setq mail-default-reply-to "me@host.xyz")
  )
)

but it does not work.
I tried some other sintaxes, with no luck.
How can it be achieved?
What's that lambda() I found in emacs manual,
I can't understand.

Can't the value of a variable be used in a hook?
Such as '(setq variable 'other-var-value) ?

Thanks,

Guldo

There are two issues here ... How to set mail-default-reply-to's value
and how to make hooks.

To set mail-default-reply-to, I guess a simple

(setq-default mail-default-reply-to "my.other.name@my.other.address")

somewhere in your .emacs should do it.

For the hook

I guess you should remove the ' before the function definition (at
least I dont have it in my own hook definitions).

This is OK, thanks.

It does not work.

In fact, what I'm trying to achieve is:
set reply-to to the active user-mail-address,
whenever I start composing a new message.
(or a reply, or a follow-up)
So that if I change user-mail-address while
vm is open, and then I compose a new message,
this new message has already a right reply-to
field in its header.

Thanks a lot,

Guldo

Yes, lambda is self-quoting.

It might be that since vm-mail-hook is run after the composition buffer
is created, it is too late to specify mail-default-reply-to for the
intended effect.  How about this instead:

(defadvice vm-mail-internal (before mail-default-reply-to activate)
   "Set `mail-default-reply-to' to `user-mail-address'."
   (setq mail-default-reply-to user-mail-address))
