    Dear Sir/Madam,

    I followed Falko Timme's tutorial of "The Perfect Server - Ubuntu Karmic
    Koala (Ubuntu 9.10) [ISPConfig 2]" to setup the ISP web hosting system, ISPConfig 2 and Squirrelmail, but I have problem when testing the email (in ISPConfig 2, create client, website, user & mail for squirrelmail etc before testing the email):

    1. in Ubuntu prompt, run "mail root" to send email message to my personal
    email address [email protected], to email address [email protected] created in ISPConfig 2 for the user & mail. But the email message could neither be received from [email protected] nor [email protected].

    2. login into Squirrlemail webmail interface and sent email message to my
    personal email address [email protected], but the email message couldn't be received from [email protected] as well.

    3. from [email protected], sent email message to [email protected], but the email message couldn't be received in [email protected].

    In all, the email message delivery into and out the email system hasn't been
    worked so far.

    It is much appreciated if anyone can help with this, e.g. the information
    guidance to identify and solve the problem; the approach to test each
    part/server in the email delivery chain to discover the issue; whatever
    helpful approach/method.

    Is it possible that you used the tutorial for ISPConfig 3 instead of ISPConfig 2?
    What's in /etc/postfix/main.cf?

    I hope you formatted the server adter you installed one ispconfig version? If not, the system will not work. You can noz install ispconfig 2 on a system were ispconfig 3 was installed before and vice versa without a complete reinstall of the operating system.

    Email delivery problem - Ubuntu Karmic Koala (Ubuntu 9.10) [ISPConfig 3]

    dear sir,

    the ispconfig 2, ispconfig 3 are installed in two different servers. the above /etc/postfix/main.cf file is for the ispconfig 3 installed in its own server. the mail.log file, post at 26th January 2010 19:25, is for the ispconfig 3 as well.

    your help with these 2 post again is much appreciated.

    thanks,
    d.s.

    We should concentrate on one server. Since your first post was about ISPConfig 2, please post the mail log from your ISPConfig 2 server.

    Are you on a dynamic IP? Most dynamic IPs are blacklisted, and there's nothing you can do about it...

    qiubosu Member

    hello falko,

    yes, i use dynamic ip. actually i have thought about that the problem might be caused by using the dynamic ip and i just want to swap it to static ip.

    thanks
     
  14. qiubosu

    qiubosu Member

    hello falko,

    for solving the problem, except of swapping dynamic ip address to static ip address, are there any other solutions instead of using static ip address?

    at the moment, it is just in the stage to test the isp hosting server, not yet in production yet, so it may not really need a static ip address now.

    your help is much appreciated.

    thanks,
    d.s.

    hello falko,

    applied a static ip from ISP, the email send & receive is ok now. but when doing a blacklist through "http://mxtoolbox.com/blacklists.aspx" with the static ip address, got the below return. does this matter?

    blacklist:219.88.70.31 blacklist

    Yes, this could be a problem. You can ask the blacklist maintainer to remove you from the list because you have a static IP.

    hello falko,

    i did another blacklist test for my static ip address 219.88.70.31, but get the same outputs (shown below) as those for the previous dynamic ip address (the one before i applied for a static ip address). so, there is no improvement when changing to static ip address from dynamic ip address. any idea?

    hello falko,

    moreover, when using static ip address, sending email from & to ispconfig server isn't ok at the moment (port 25 open), the same as when using the dynamic ip address. but when just swapping from dynamic ip address to static ip address, sending email from & to ispconfig server was ok before (haven't done any change/update with the ispconfig server since swapping to static ip address). any idea on this?

    thanks

    It seems as if the static IP given to you by your ISP is from dynamic IP pool and therefore blacklisted. I doubt that you can do anything about it.
