I am using RC 1.1.3 on CentOS server.

My mail server is Dovecot.

One of my customer is complainig about an issue during searches through webmail interface.

The error he get is:

[11-Nov-2015 16:35:41 +0100]: <nn2tv074> [DB20] S: A0005 BAD Error in IMAP command UID SEARCH: Unknown argument INBOX

He has no problem in folders other than INBOX (I mean: sent, trash, and so on).

How can I solve this?

Thank you very much
