My Mail Client (emClient) generates an error:

[IMAP]The folder “/Public” cannot be opened. (NO [NOPERM] Permission denied (0.001 + 0.169 + 0.169 secs).)

Within my server no public folder exist. That means, mail server provides non exisiting folders.

How to fix it?

Hm, emclient looks nice but it seems there’s no possibility to choose/subscribe to IMAP folders so we need to fix it on the server.

I needed to set the public folder to allow lookup and read for authenticated users, after that change emclient didn’t complain anymore.

doveadm acl set -A Public authenticated lookup read

I am also surprised that emClient has this lack. I have pointed it out to the developers there again.

Thanks for your workaround.
Best regards, MArko
