I am able to receive emails in outlook express using either www.mydomain.com
or server1.mydomain.com but pop3.mydomain.com doesn't work so is smtp.mydomain.com for sending mails.
DNS records in ISPconfig Box
Configuration at my domain registrar's Cpanel
184.108.40.206 (my static IP assigned in router)
if i use pop.mydomain.com in outlook express for receiving mails it returns this error
The host 'pop3.mydomain.com.com' could not be found. Please verify that you have entered the server name correctly. Account: 'Work', Server: 'pop3.mydomain.com', Protocol: POP3, Port: 995, Secure(SSL): Yes, Socket Error: 11004, Error Number: 0x800CCC0D
or server1.mydomain.com works fine.
I am able to ping both pop3.mydomain and smtp.mydomain.com from another machine(win) in my LAN if it's DNS server is set to my ISP DNS servers but it fails if the DNS server is set to ISPconfig Box.
port forwarding is also done for ports 25,110,995.
How can i fix this?
