    Today i found out that on one of my servers, i can not establish a connection via IMAP.

    The portscanner within the ISPConfig (on the server itself), shows that the following IMAP ports are open:

    Port 143 (tcp) is open (imap2)!
    Port 993 (tcp) is open (imaps)!

    netstat -tap | grep imap shows me:
    tcp6 0 0 *:imaps *:* LISTEN 1980/couriertcpd
    tcp6 0 0 *:imap2 *:* LISTEN 1968/couriertcpd

    But when i try to establish a connection via telnet from my local desktop with:
    telnet 12.34.56.789 143

    It fails...:(

    The firewall on port 143 within ISPConfig is disabled.

    Within Outlook Express i receive the error code: 800ccc0e
    This means that a connection is not possible.

    My conclusion is that i can not establish a connection via port 143 from outsite the mailserver.

    Any suggestions to solve this problem?

    For me the cause of this temporary problem, is unknown, but i solved it by restarting the firewall on that mailserver within ISPConfig.
    Everything is fine again! :)
