    hi all I have a problem with the email of ispconfig 3 I can send emails but I can not get them.

    I have a server that I am using router all port as much as 80 to 8080 and those for the OPERATING of ispconfig 3 are routed to the server.

    the question is ...

    that I can not receive? :mad:

    HowtoForge follow the guide of ispconfig 3 with dovecot bind and step by step and is installed correctly ....

    the operating system is debian 5.0 Lenny

    I am using iptables

    would greatly appreciate the help

    Thanks!!

    Are you able to send yourself a email locally from one account that is hosted on the server to another account which is hosted on the same server?

    I think that you have a problem with DNS. Chech if you have a corect pointing to your server.

    Thats good as it indicated that the problem is not the mailserver. As Ghostdare pointed out, you should check your dns records. Additionally, make sure that you forwarded port 25 from your router to your server and that your internet access provider does not block port 25.

    I'm not an IPTABLES familiar but try to stop this service, for testing only, and give a try. maybe somebody else will give you an opinion about your configuration.

    Help me!!!!!!!!!!!!!!!

    Merry Christmas for all!!!!!!!!!!!!!!!

    Hello Ghostdare

    you were right the problem is not resolving dns

    stop the configuration of the firewall (iptables) and check port redirection was fine 25y

    could you tell me how to configure DNS for that I have reviewed to my knowledge but nothing does not work the connection.

    can you tell me which file I edit?? and if you can show me a dns configuration file to guide me ....

    Thanks!!

    Merry Christmas... sry for my late response, i was Internet free these days.

    1. Your server has a FQDN?
    2. Has a NS at your registar or do you use your srv as primary nameserver?
