Mailkit: IMAP server returns [SERVERBUG] when performing a search

Created on 30 Mar 2019  路  7Comments  路  Source: jstedfast/MailKit

My code: 

var folder = client.GetFolder(SpecialFolder.Trash);
folder.Open(FolderAccess.ReadOnly, cancel.Token);
var uids = folder.Search(query);

Look at this screenshot http://prntscr.com/n4yp68
Not exist folder "INBOX"

error in this part of code - var uids = folder.Search(query);

Exception text -"The IMAP server replied to the 'SEARCH' command with a 'NO' response: Internal error occurred. Refer to server log for more information.

Ok, the [SERVERBUG] response-code suggests that the server developers are aware that the syntax MailKit is using is correct but they aren't handling it (yet?).

After authenticating, try adding this snippet of code:

client.Capabilities &= ~(ImapCapabilities.ESearch | ImapCapabilities.SearchResults);

What I think is happening is that the server is breaking because MailKit is using the ESEARCH/SEARCHRES search syntax (RETURN ()).

You can see where the code adds that part of the query string here: https://github.com/jstedfast/MailKit/blob/master/MailKit/Net/Imap/ImapFolderSearch.cs#L654

The above code snippet essentially disables those SEARCH extension features so that MailKit won't attempt to use them.

That should work around the issue for you, I would think. Let me know how that goes for you either way.

You might need to contact your mail server admins and ask why you are getting that error. I don't know what else it could be.

Looks like the server might be Dovecot based on the error text: https://wiki1.dovecot.org/Logging
