[O] Links for getting email in Gmail (IMAP) with Gnus ?

[Joseph Vidal-Rosset]

Hello,

I know that it is possible to link emails in Todo list, but I meet
difficulties with Gmail IMAP and Gnus when the mail is in the box "All
emails" ("Tous les messages" in French): as soon as the email is in this
Archive, the link is broken and Gnus does not fetch it.

Help and code are welcome.

Best wishes,

Jo.
