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:

http://www.zimbra.com/forums/install...querading.html

But the problem continues.


My server configuration:

zimbra@zcs:~$ zmcontrol -v
Release 6.0.9_GA_2686.UBUNTU10_64 UBUNTU10_64 FOSS edition.

zimbra@zcs:~$ cat /etc/hosts

zimbra@zcs:~$ hostname -f
zcs.z.ventura-systems.net

zimbra@zcs:~/postfix/conf$ cat main.cf | grep masque
masquerade_domains = zcs.z.ventura-systems.net z.ventura-systems.net

zimbra@zcs:~/conf$ cat postfix_header_checks.in

Thanks for your help,

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:

127.0.0.1	localhost

should look like this:

127.0.0.1	localhost.localdomain localhost
