Able to send out but not receive emails

[freezefusion]

Hi,

My users are able to send out emails from roundcube mail but are unable to receive anything.

Outlook express is not downloading any emails nor allowing it to send out either.

Error message that is received is :

Your server has unexpectedly terminated the connection. Possible causes for this include server problems, network problems, or a long period of inactivity. Account: 'mail.blitz-me.com', Server: 'mail.blitz-me.com', Protocol: POP3, Port: 110, Secure(SSL): No, Socket Error: 10053, Error Number: 0x800CCC0F

Another error message received is:

Task '[email protected] - Receiving' reported error (0X800CCC0F) : 'The connection to the server was interrupted. If this problem continues, contact your server administrator or Internet service provider (ISP).'

Please guide.

# telnet localhost 110
