    Postfix config

    Can you copy some of your log files in here, preferably your postfix, and from restart of postfix to up and running...
    Can you also so a netstat -ant and copy in the contents?

    Okay it looks like its not just my mail. Mail gets delivered just a few hours later. For some reason, the entire machine has started to slow down today. I attempted to login via ssh and the username & password came up pretty quick but then it took a few seconds to get the command line to appear. So I decided to logon to the machine its self and same thing. Websites on the server are running slow remotly, just everything has kinda crapped out. Any help would be great... customers are about to kill me ehhh

    Heres the command top output

    ??? Is that high of a number normal when you host about 20 sites with only a few e-mail accounts? Doesn't seem right to me... ahhh where is everyone... need help. Need to figure out how to make the server move these messages faster

    tried to reinstall ispconfig thinking it might reconfigure something and then it crashed through install. Now when I start I get

    Executing /etc/rc.d/init.d/ispconfig_server start ..


    Starting ISPConfig system...
    /etc/rc.d/init.d/ispconfig_server: line 45: /root/ispconfig/httpd/bin/apachectl: No such file or directory
    /etc/rc.d/init.d/ispconfig_server: line 47: /root/ispconfig/php/php: No such file or directory
    FreshClam is already running!
    ISPConfig system is now up and running!

    though its not really running. When I go to reinstall its acting like a fresh install rather than an upgrade now.... is there a way to get this to install as a upgrade again and get my system back online... . ahhh everything is a mess

    It seems as if your system is abused by spammers. Make sure you're not an open relay.

    Your problem has nothing to do with ISPConfig...
    Please check the /tmp directory. There should be backups of your last working ISPConfig installation (a tar.gz of /root/ispconfig, a tar.gz of /home/admispconfig, and an SQL dump of the ISPConfig database).

    Thank you so much for helping me get the ispconfig control panel back up and running. It also started my httpd which wouldn't start. Thats GREAT! :) However, I am looking in to the e-mail problem, I followed the guide to a perfect setup but when I attempt to telnet in I run the ehlo localhost command and I get:

    500 Error: bad syntax

    Any ideas? Also is there a command to make the e-mails process at a faster rate?

    Thank you so much for your help

    Is there anyone willing to login to my server and see if they can get postfix running correctly? I would appriciate it sooo much.. I don't think I can handle these customers much longer. I see nothing in queue yet mail won't deliver for hours later... when i went in to the directory I see loss of files in the queue folders. and today mail started bouncing again and I think smtp stopped.... ehhh

    I reinstalled postfix and still bouncing but I got a ehlo reply thats good

    Trying 127.0.0.1...
    Connected to localhost (127.0.0.1).

    Problem Fixed: After look through this server one other person had the same error as I did but different issue. I was able to look at his config and notied I a missing a lot of things. I added

    virtual_maps = hash:/etc/postfix/virtusertable
    mydestination = /etc/postfix/local-host-names
    alias_maps = hash:/etc/aliases
    alias_database = hash:/etc/aliases

    To my config which started accepting mail. But I think I am still missing things. I know things are working now but I don't want to get errors in the future. Can someone please look at my config file and let me know what I need to add?

    That link is very slow.
    What's the output of

    and

    This setting allows the 66.214.254.16/29 subnet to send emails without authentication. Most probably your server is abused by spammers from this subnet.
    Please run
    Code:
    postconf -e 'mynetworks = 127.0.0.0/8'
    and restart Postfix. Then only localhost can send without authentication.
