I installed VirtualMin on a VPS running Ubuntu. Then I installed RoundCube using script on VirtualMin.
I created a new one Email account (Edit Users -> Add a user to this server) and enabled IMAP client (Enable mail client autoconfiguration? = Yes).
But when I log into email accounts with RoundCube the error: "Connection to IMAP server failed". I've used Thunderbird but it also connects error.
How fix it? Please help me.
