Issue After latest Plesk/Dovecot update, duplicate spam, sending, deleted items.

Plesk version and microupdate number

Hello everyone, I would like to remove the duplicate folders. Unfortunately, these folders are not being deleted. Now I have the following folders duplicated: Drafts, Spam, Deleted Items. How can I restore the order? See image. In addition, Roundcube uses the folders under the inbox, and Outlook, iOS, and Android use the other folders. What can I do?

Hello, @B1G-OS . It doesn't seem like the image is successfully attached. Are the duplicate folders present in Roundcube as well or only on Outlook?

 

[B1G-OS]

The folders are in Roundcube and Outlook. I tried to delete the folders in the Roundcube settings. Unfortunately, these folders keep getting recreated.

Thank you for the update. Could you please try the workaround (solution 2) from this article and let us know if it makes any difference with the folder structure and the duplicate folders:

Thanks for your feedback. Unfortunately, that has nothing to do with it. Even if Outlook is not running and you only log in via Roundcube, you cannot remove these folders. When I enter “inbox” in Outlook, the other folders I created myself are no longer displayed. Then I only see the subfolders of the “inbox” inbox. Where can I delete the duplicate folders? It's not possible in Roundcube, and it's not possible in Outlook either.

I found the change. How this change came about and who made it is now irrelevant to me.

In the file: defaults.inc.php under /usr/share/psa-roundcube/config
The subfolders were created in the Roundcube settings and therefore could not be deleted.

The folders are listed from around line 920 onwards.
Before my change: INBOX.Sent, INBOX.Drafts, INBOX.Spam, INBOX.Trash.
After my change, I simply rewrote the folders with a slash (/) without INBOX “/Sent.”

Now the folder structure is back to how it was before the update. However, it should be noted that when you log back into Roundcube, you can set the fixed folder options under Settings. “Settings/Special Folders.”

I really feel like you're messing with me. Why are you changing users' personal settings?

What's the point of that?
# Plesk uses INBOX.Spam as hardcoded delivery folder
mailbox INBOX.Spam {
auto = create
special_use = \Junk
}
I can't change this setting because otherwise Sieve won't work anymore. Can you please fix this? And also set Sieve back so that there is only one spam folder and not an INBOX.Spam folder?
Neither my customers nor I want that.

In addition, you forgot the entry in “93-kolab-antispam.conf”:

sieve_global_extensions {
vnd.dovecot.pipe = yes
vnd.dovecot.execute = yes
}

Sieve did not filter the spam files correctly and displayed errors. I don't understand how this could have happened. I spent half the day searching for the errors, not to mention that personal folder settings can easily be changed. I have never had such serious problems with Plesk in more than 10 years. This should not happen.
