How to use GNUS with Gmail?

Question

I searched for several mail clients but all are messed up. The best I could find was gnus which I managed to configure to retrieve data from Gmail. However:

1. When I read message in gnus, it is still marked as unread on gmail
2. I couldn't find how assign labels to emails
3. I couldn't find how to sort or delete messages (preferably using key binding)?

I think that my problem is that gnus uses newsgroup terminology which confuses me.

Is there any tutorial online which focus only on this?

The problem I have is how to test.

Answer 1

I'm surprised by your 1, because when I read mail in gnus, they are marked read in gmail.

For the rest, gmail maps labels to IMAP folder, so

B m nnimap+gmail:commande

Will move the article to the commande label, and mark it with the commande label. GNUS will create the folder if needed.

Probably, copying the mail with B c will add the label, but I don't use it.

B m nnimap+gmail:[Gmail]/Trash

will put it into the trash folder, and so delete it.

Deleting it with B Del or using expiry (E) will just remove the label or archive the message. I've setup:

(setq gnus-parameters
      '(("nnimap\\+gmail:INBOX" (expiry-wait . 2))))

This will archive message marked for expiry two day after they have been received.
