IMAP not working with GNOME Evolution client

[gitkrakel]

When I try to connect to IMAP using GNOME Evolution, it does not get back the Inbox folder. Instead, it gets back a folder named *"INBOX" with no messages inside.

Below is the traffic between the SMTP server and the email client (click arrows to expand):

Client to SMTP

``` A00520 CAPABILITY A00521 LOGIN local 1234 A00522 CAPABILITY A00523 ENABLE UTF8=ACCEPT A00524 LIST "" INBOX A00525 LSUB "" INBOX A00526 LIST "" INBOX A00527 LSUB "" INBOX A00528 LIST "" "*" A00529 LSUB "" "*" A00530 LIST "" INBOX A00531 LSUB "" INBOX A00532 STATUS "*"INBOX"" (MESSAGES UNSEEN UIDVALIDITY UIDNEXT) A00533 SELECT "*"INBOX"" A00534 UID FETCH 1:* (UID FLAGS) A00535 IDLE ```

One workaround is to create an account in Evolution that connects to another IMAP server to populate the folder list, then switch the server address to smtp4dev's IMAP server. Then I can retrieve messages in the Inbox folder from smtp4dev. However, as soon as I "refresh" the account in Evolution, it tries to get the list of folders again and the Inbox folder disappears.

Thanks for the detailed report. I believe it's the LSUB response not being implemented that is causing this.

Resolved in PR #1469

This guess was wrong. It's something to do with the UTF-8 capability support in Evolution or the IMAP library we derived from. The *" should not have been displayed in Evolution as part of the folder name. Since it's only sending folder name INBOX not losing anything by disabling it.

Confirmed working on my side. Thanks for the quick turnaround!
