    I have installed ISPCONFIG last year, everything has been working properly until one day I got a message that Clamav is OUT of date. Since then my machine slowed down and all the mails were rejected.
    I uninstall clamav and installed the latest version and everything went fine again.

    The same problem happened today but this time I keep getting this message
    delayed SMTP module(domain xx.com) reports:
    mail.xxx.com: connection refused

    Can anybody help?

    from clamav:
    ERROR: getpatch: Can't download daily-9243.cdiff from db.local.clamav.net
    Ignoring mirror 130.59.10.36 (too often connections with outdated version)

    ERROR: getpatch: Can't download daily-9243.cdiff from db.local.clamav.net

    When I rebooted the server it freezed after load ISPCONFIG. What do I do to make it go beyond this?

    I also ran a netstat -tap got this as answer
    tcp6 ....:pop3 ..... TIME_WAIT

    When I run telnet localhost 25, it works then when I do ehlo localhost, I get timeout exceeded.

    The server has become very slow to work with. It takes about 1 minute to display only one letter that I typed.

    Can anybody please help?

    when doing netstat -tap

    I also see sth like

    smtp cenmail2.ceridia 56746 ... listen

    there are other ip addresses that I do not know. How do I delete them and block them from using my smtp to spoof my mail server?

    I'd reboot the server and then use rkhunter and/or chkrootkit to check if there's malware installed on the system.
