So the problem is that when I send a draft, its content is subject
to expiry, and this does not work because a draft is not like
a normal article (and with the "G c" below we tell Gnus to delete
and not expire sent drafts)?

Yes, I am doing that:

(setq nnmail-expiry-target "nnml:expired")

Thank you, that looks good, I'll try that!

If that works, then I think it's a good idea to mention this problem
in the Gnus documentation?

Many thanks again and Best Regards,
