Sounds like a network firewall issue. Webmail is hosted on local server (iRedMail), so there's no firewall at all.
Did you check your network firewall rules? Does it bypass necessary network ports? e.g. smtp (25, 587), imap/pop3, etc.
Well I have disabled the firewall. But still not working. Please let me know if there is anything required from IRedMail configuration?
