[Solved]Mail from Postfix goes into spam in gmail

Hello, I setup Virtualmin in centos 6. I have setup a SOA as follows: v=spf1 a mx a:domain.com mx:domain.com ip4:x.x.x..34 ip4:x.x.x.35 -all

But all mails sent to a gmail account go to spam. The info in gmail is as follows:

Hmm, I don't see any obvious issues in the above.

I believe Gmail started tagging emails with some information about why they were put into the spam folder... do you see anything like that if you look at this message in your spam folder?

Also, you could always try going to a site such as this one to see if you're on an RBL:

Hello, Well, my host is not in any blacklist...

See if you can enable DKIM (Email Messages-->DomainKeys Identified Mail and put that into the TXT record of your domain/s, at least that worked for me.

Hello, I have enabled DKIM for my domain. Its added to the DNS record now. I will wait for a while and check whether the emails go to spam in gmail or not. Thanks for the suggestion though :)

When I try Email Messages -> DomainKeys Identified Mail I get the message "DomainKeys indentified mail is not available on this system" and an offer for Virtualmin to auto install. When I click the install button I get these errors:

Installing the DKIM filter package ..

Installing package(s) with command yum -y install dkim-milter ..

Error: Cannot retrieve repository metadata (repomd.xml) for repository: virtualmin-bleed. Please verify its path and try again

.. install failed!

.. installation failed!

I tried finding a virtualmin bleed for CentOS 6 but cannot find one.

Is there a way I can get DKIM without virtualmin bleed or do I need to try something else?

Thanks, Ken

Does this work only when BIND is enabled ? I tried VirtualMin's DKIM and I get that no virtual server is configured to DNS and Email. Maybe because I use my host's DNS ? Thanks!

Best Regards
