[Skunkworks] Challenging situation

Morning Skunks, Am having a challenging situation with my Mails.i cant send/receive while on my LAN But am able to access my Mails on my mobile devices without any Qualms. When i try to Access my Webmail+Cpanel on any Machine in my LAN am unable to reach it but possible on my mobile device and outside our LAN.Thats why i don't think its an issue my Mail Host. Am beginning to its my Firewall which is blocking All the ports associated with Mail server. Anybody who has experienced the same or is there a Cyberoam Guru around?
