We can eliminate these by using autoloads. canlock is used for news
postings in Gnus by default. Hashcash is an optional feature for
mail.

[mailheader.el is not part of Gnus, but part of Emacs.] Required to
insert correctly formated (quoting, folding, ...) headers into mail
message buffers.

[mailutils.el is not part of Gnus, but part of Emacs]. It provides
utility functions for mail handling. Both, rmail.el and sendmail.el
use it. I see no point in avoiding using it.
;;; mail-utils.el --- utility functions used both by rmail and rnews
[...]

I will try to eliminate this dependency.

Handling expansions of mail aliases.

For parsing and encoding headers and body correctly.

Required for MIME handling (e.g. sending attachments).

[rfc822.el is not part of Gnus, but part of Emacs.] Uses to ensure that
address headers are RFC822-compliant. Is also used in rmail.el.
> (require 'ecomplete)
We can eliminate these by using autoloads. ecomplete is optional.

Doing all aspects of MIME mostly correct is not quite simple. Many
MUAs (Mail User Agent) have severe bugs WRT this. When reading about
non-trivial topics in the relevant newsgroups, most of the time only
mutt and Gnus do the right thing.
Bye, Reiner.
