How to know a mail is sent with gnus ?

How to know a mail is sent with gnus ?

[Francis Moreau]

Hi !

I'm writing a hook for 'message-send-hook' and I would like to know from
this hook if the current message has been sent by Gnus.

Could anybody tell me what I can test ?

Thanks

Sent by Gnus in contrast to rmail, which also started using message-mode
recently, right?

At least `org-gnus.el' checks for Message-Id and Gcc headers to store
links to Gnus messages that haven't been sent at the time of linking
yet.  I might be wrong, but I think Gcc headers are a Gnus invention.

Bye,

You're right.

The thing is that I don't always use Gcc header. For mailing lists for
example, I don't use it since I'm going to receive a copy of the mail
anyways.

Why do you need to know that?

Hm, I always set a Gcc.  For normal groups it's the group itself, and
for mailing list groups, I set a Gcc to my "Sent Messages" group.

Instead of looking at the Gcc, you could set
`message-generate-headers-first' to t and make User-Agent non-optional
in `message-required-mail-headers'.  That should insert a User-Agent
header with Gnus + version as contents as soon as you write a mail from
inside Gnus.

HTH,

Hmm, I think I could use the "Sent Messages" group for mailing list
groups.

Ah, that's another possibility which sounds good.

Thanks Tassilo for your suggestions.

Because I have this in my .emacs:

  (setq mail-default-headers
        (concat "Bcc: " user-mail-address "\n"))

that is I want to receive a copy of my emails sent from emacs but not by
gnus itself.

When writing stuff with Gnus, I prefer to use Gcc header. Therefore when
I'm writing email from Gnus, I want to drop the Bcc header automatically
set.

Perhaps a call to message-remove-header in message-setup-hook will work?

But isn't that new hook be installed for my whole emacs session ?

Yes, sorry, I should have said gnus-message-setup-hook, which I would hope that other modes that use message do not call.

Ah, yes indeed that's a good idea, assuming that no other modes call
this hook, but that would be pretty silly I think.
