JAY way past over that dude. I am familiar with AAPanel. The error was I manually deleted the database because roundube was keep showing sending email and was not sending emails. I thought I could fix the problem by reinstallation I am using AWS instance and mails using relay. I am still struggling with the problem. The SMTP is able to send emails but roundcube cannot. I can still send emails using the mailserver interface. Can you please help with that??
Thanks for helping..
