Mails working randomly

    Hello.

    I configured a Debian server with ISPConfig following the complete guide "The Perfect Setup - Debian Etch".
    I host several sites on this server. Websites are working but that's not the case concerning emails.

    Imagine I have two websites, emails should be like this :
    1. first.com : using Google Apps :
      • Remote Mailserver
      • no Mx record
    2. second.com : redirects to first.com's Google Apps :
      • Local Mailserver
      • MX record
      • Email redirection in the user ISP settings

    The problem is that it seems to work randomly. Once it redirects and everything is ok, once it gives
    Code:
    <[email protected]> (expanded from <[email protected]>): unknown user: "user1"
    Any clue about this ? I completely re-installed the private server twice but it still doesn't work. Thank's a lot.

    PS : sorry if my English is bad. ;-)

    I just made a quick test. I sent 4 mails to the same second account. The result is :
    • 2 mails well redirected
    • 1 mail was in the local inbox (RoundCube)
    • 1 mail gave an "undelivered..."

    What happens ?? How is it possible ?

    What's in the mail log when an email ends up in the local inbox and when you get an "undelivered"?

    Thank you for the answer.

    Well, right now I don't receive them locally on the server. Only "undelivered" :
    Code:

    Plus, if I ask for a redirection to a normal Gmail address, it works fine.

    But it doens't work with a Google Apps account with MX configured on the server. It seems the server looks for the Google Apps account ([email protected]) on the the server, in the undeliverd mail :
    Code:
    <[email protected]> (expanded from <[email protected]>): unknown user: "user1"

    Please make sure your server isn't blacklisted: http://mxtoolbox.com/blacklists.aspx

    Checked. No, it isn't blacklisted...

    Do your email domains have SPF records? Does your mail server have a PTR record?
