    Hello.
    Recenty, my postfix installation has lost its capability of sending and receiving emails from outside localhost. I have made no changes to its previously working configuration or to my firewall. Even so, I have lost sending and receiving capabilities.

    /etc/postfix/main.cf
    Code:
    # See /usr/share/postfix/main.cf.dist for a commented, more complete version
    
    
    # Debian specific:  Specifying a file name will cause the first
    # line of that file to be used as the name.  The Debian default
    # is /etc/mailname.
    #myorigin = /etc/mailname
    
    smtpd_banner = $myhostname ESMTP $mail_name (Ubuntu)
    biff = no
    
    # appending .domain is the MUA's job.
    append_dot_mydomain = no
    
    # Uncomment the next line to generate "delayed mail" warnings
    #delay_warning_time = 4h

    I'm new to linux and server administration so I'm not sure if I found anything interesting but in the /etc/postfix/ directory there are the files:
    Code:
    -rw-r--r-- 1 root root     3701 Mar 13 22:29 main.cf
    -rw-r--r-- 1 root root     3634 Mar 13 22:29 main.cf~
    -rw-r--r-- 1 root root     3701 Mar 13 22:29 main.cf~2
    -rw-r--r-- 1 root root     3702 Mar 13 22:29 main.cf~3
    -rw-r--r-- 1 root root     6388 Mar 13 22:29 master.cf
    -r-------- 1 root root     6388 Mar 13 22:29 master.cf~
    -r-------- 1 root root     6388 Mar 13 22:29 master.cf~2
    
    Are the files with the tilde temporary files? If so, why would there be temporary files of a configuration file?

    canyouseeme.org reports that it cannot see me on port 25, but it can see me on port 587. This is because my ISP, comcast, blocks this port. I have to use their smtp server, which I believe to be smtp.comcast.net, for outgoing mail on port 587. As I have stated before, this was a working postfix configuration to which I have made no changes. However, now I can no longer send or receive email. Would buying a smarthost service like that provided by dyn.com prevent this failure in the future? Any help is greatly appreciated.

    I hope the outputs reveal what's wrong. I had to shorten the output of mailq as it was 898 Kbytes and this forum wouldn't let me post the message.

    well... As you said, your mailq is tooo big.

    Run
    Code:
    postsuper -d ALL
    and try again. Be aware, it will delete all mailq entries.

    Okay. I ran sudo postsuper -d ALL and then ran mailq:
    Before doing that though, I ran sudo postsuper -d ALL and I tried to send a message from my server machine and it did not reach an outside email domain. I tried to send from an outside email and it did not reach my server machine. I then ran sudo postupser -d ALL again and then provided the output of mailq in the above quote.

    I followed the ubuntu perfect server guide if that changes any filepaths. I checked in my mail client and I did receive the email though.

    Are you sure that port 25 is open in the ISPConfig firewall panel? (System->Firewall->Choose your server and look for 25 in Open TCP ports and Open UDP ports)

    Try to disable SELinux.
    Code:
    sudo echo 0 > /selinux/enforce
    Code:
    reboot
    It should help :cool:

    Okay I added the entry to my firewall but for the selinux command I get this error:
    Code:
    -bash: /selinux/enforce: Permission denied
    
    After adding the firewall rule, I can no longer get my mail client to connect to my mail server. Mozilla Thunderbird just hangs at connected to mail.mydomain.com

    You had just to add port 25 to the firewall. If you did it, than it has nothing to do with your mail. If your mail doesn't work, it may be your own fall in typing ports, or SELinux. In any way, try to send mail. If it doesn't work, than turn the SELinux on and we will wait for Till :(
