If your MTA is delivering mail directly to your maildir, you should not
also be using the same Maildir as `mail-sources'.  This will cause Gnus
to process the mail twice, with potentially inconsistent results.

As noted in the Info documentation:

(info "(gnus) Maildir")

If the MTA is delivering mail directly to the maildir at ~/Mail/, you
only need the following:

(setq gnus-select-method
      '(nnmaildir ""
		  (directory "~/Maildir/")
		  (get-new-mail nil)))

`mail-sources' should also be nil.  This variable is only useful when
you want Gnus to "pull" the mail from some location, such as an mbox,
pop server, or Maildir at a remote site or elsewhere on the system; it
should not be used when the mail is "pushed" directly to the very same
location where Gnus is storing it.

> (setq gnus-message-archive-group "nnmaildir+inbox:Sent/cur")

is also a bit odd.  You're telling it to use the nnmaildir server
"inbox", which in your config doesn't exist, and you're also telling it
to use a specific subdir inside the maildir, rather than the maildir
itself.

I would rewrite this part of your config as

(setq gnus-message-archive-method gnus-select-method
      gnus-message-archive-group "Sent")

This is very close to the config I use myself and I love it, so I hope
this advice helps.
