Hello, Good Day to everyone! I am a newbie in Linux. I was setting up Mailserver for our website in school. I am using Postfix as MTA and Dovecot. I also install AtMail as my webmail client to send and receive emails. I was able to login and read email messages for a week, then after a while I wasn't able to login to my mailbox coz as I enter my username and password, a message says "Server Responded: -ERR Connection to IMAP Server Failed" Can you please help me with this problem? Thanks and God Bless!
