[Users] CC mail with newsgroup and mail account

[Marco]

Hi,

I  have a  gmane account  for reading  and writing  usenet
posts. I often want to send a copy of the mail directly to
the person taking  part in the conversation.  But I cannot
send emails from the gmane account.

My workflow at the moment is:

∙ Compose and send usenet message using the gmane account
∙ Open the message just sent  and change the account to
  <my_mail_provider>  and   the  address to
	<conversation_partner>.

What I would like to do is

∙ Compose usenet message using the gmane (newsgroups)
  account
∙ Add recipient to CC
∙ Send the message using the gmane account and the CC mail
  using my mail account

I don't know if that's possible. I wonder how other people
solve this. Any suggestions welcome.

Marco
