    Default Gmail, Hotmail and Yahoo, detect my mail as spam

    Hi, how are you?

    Gmail, Hotmail and Yahoo, detect my mail as spam.

    I installed Zimbra, receive mail correctly, but when trying to send to Gmail ... mail is detected as spam, while the MTA shows sensitive data:

    I have carefully read this article:

    But the problem continues.

    My server configuration:

    zimbra@zcs:~$ cat /etc/hosts	localhost	zcs
    zimbra@zcs:~$ hostname -f
    zimbra@zcs:~/postfix/conf$ cat | grep masque
    masquerade_domains =
    zimbra@zcs:~/conf$ cat
    /^Received: from .+\..+\.z.ventura-systems\.net .+(by zcs\.z.ventura-systems\.net .+) / REPLACE Received: $1

    Might it be the fact you don't have a reverse DNS record for that server? Where is the evidence in those headers that gmail thinks your post is spam?

    BTW, the link for the post you've asked to be removed is invalid and your hosts file is also incorrect. The following line:

    Code:	localhost
    should look like this:
    Code:	localhost.localdomain localhost
