I am unable to log in to my email. Upon checking the backend logs, the following error was found:
mail roundcube: IMAP Error: Login failed for mengchaosunftswcc.com from 61.241.70.233. Empty startup greeting (127.0.0.1:143) in /var/www/roundcubemall-0.7.2/program/include/rcube imap .php online 205 (posT /mail/? task=logins action=login)
I hope someone can help me, thank you!
