Hi.
One of my client have installed Roundcube Webmail system to their panel as a mail module. It was working properly, but recently I am getting an error like this IMAP Error: Authentication for xxxx.xxx.xxx@xxxx.xxx.xxx failed (LOGIN): "a001 NO Login failed: authentication failure". I searched a lot on this issue, but couldn't find any fix.
Can anybody please help me on this? The system was setup by my client and I am web developer, I am not much aware about the admin settings of this webmail and how he configured this? If you have any idea about this issue, please help me.
Thanks All
