    Hallo,


    ich habe bei mir auf dem Server mehrere Domains und natürlich zu den Domains auch Emailadresse eingerichtet.
    Für die Emailadresse einer Domain habe ich einen Exchange-Server angemietet und leite über eine NS-Eintrag die Mails direkt an diesen Exchange um.
    [email protected] -> MX 10 ...Exchangeprovider...


    Das ganze funktioniert auch soweit ganz gut wenn die eMails von 'außen' kommen.
    Wenn ich aber nun eine Mail von einer der anderen Domains an dieses 'Exchange-Email' [email protected] senden will, dann landet diese immer auf dem iMSCP-Server im Mail-Postfach und wird nicht an den Exchange weitergeleitet.


    Ich gehe davon aus, dass interne Mails keine NS-Auflösung machen und daher die Mails einfach ins Postfach gelegt werden.
    Ist das so?
    Kann ist das ändern?


    Vielen Dank
    Gruß


    System:
    iMSCP 1.3.16
    Debian Wheezy

    Hello,


    I checked the neighbour IP addresses with the symantec tool and also they had the same reputation error... as written before.
    So I talked to the server provider and they talked to Symantec and my server is released.
    If I check my IP now it looks good.


    But I still have the feedback 'refused to talk to me' in the log file for some emailsadresses...
    Any idea?


    Thanks

    Hello,


    for me it's not clear why my server is listed on the Symantec Reputation.
    I checked my sverer with the other links you have written in this threat and it looks good to me.


    Furthermore other IP in the same range (85.25.108.173, 85.25.108.172, 85.25.108.174, ...) have the same answer on Symantec Reputation...


    As I have written I have checked my server by antivir and cannot find any problems.


    Could you please check and give me a feedback if it could not be an issue on the email handling of IMSCP or is it a problem of the IP range my server belongs to?


    Most of the mails are not affected and will be delivered to the target email adress.
    I have regonized the problem only on one or two domains, which are email addresses of 'big' companies.


    Thanks a lot
    Regards
