Hi,

new install of 0.40 on clean Ubuntu 18 . admin seems to be working fine , however Webmail , or IMAP is not . if i try with roundcubemail :

**IMAP Error in /usr/local/lib/roundcubemail/program/lib/Roundcube/rcube\_imap.php (196):** Login failed for my@email.here from xx.xx.xx.xx. LOGIN: Login failed.

i also see in roundcube/imap when debug enabled :

[18-Feb-2019 17:58:07 +0200]: [8913] S: \* OK [CAPABILITY IMAP4rev1] Courier-IMAP ready. Copyright 1998-2005 Double Precision, Inc. See COPYING for distribution information.

Is there any slight possibility that the authentication details were entered incorrectly? Cap locks key on, or something similar?

Perhaps add a second user and see if the issue persists.

Also non-US characters in usernames and passwords can be a problem.

nope, just created a test user with test1234 password - same result .  
weird, only log form roundcube is being produced , mail.log says nothing - last info - dovecot restart.

How can i check if IMAP works at all ?

Found this line as well , not sure if it can be the reason  
doveconf: Warning: SSLv2 not supported by OpenSSL. Please consider removing it from ssl\_protocols.

Attempt logging in with a different client such as Thunderbird.  
Alternatively see if the server is responding by trying to telnet to it:  
telnet box.domain.al 993

Aha, fixed it !

I think developers should check if localhost is defined in hosts file . In my case as WEB is hosted separate i had :

using external DNSes :

xx.xx.xx.xx [mydomain.com](http://mydomain.com)  
xx.xx.xx.xx \*.mydomain.com  
thus whith wildcard domain settings

then i installed mailinabox to yy.yy.yy.yy IP:  
yy.yy.yy.yy [mailinabox.mydomain.com](http://mailinabox.mydomain.com)

and somehow my hosts file had missing  
127.0.0.1 localhost  
entry

thus using wildcard DNSes localhost where resolved to [localhost.mydomain.com](http://localhost.mydomain.com) -\> xx.xx.xx.xx , outside of the mailinabox. and thats where roundcube where trying to connect 🙂

Thank for help !
