Webmail provided with zpanel (roundcube) works but from my understanding it uses the send email php function or localhost to send emails. I need a working email server STMP + IMAP to send email with thunderbird and various online apps. I tried different settings smtp.mydomain.com, various ports but this doesn't work. If any of you guys knows what the issue is i thank you in advance but please don't post ignorant answers such as don't use zpanel it adds another layer of complexity. Thanks, Robert
