Make sure your ip is not blacklisted or with bad reputation.

Checking Senderbase (https://www.senderbase.org/lookup/?searc...38.182.138) does not look bad at all.

Are you sending to Gmail?
What is the reason gmail tells you for it going to spam? (please refer to: http://www.whatcounts.com/2012/03/gmail-...marketers/)

Does it only happens on Gmail?
One tool I found usefull is https://www.mail-tester.com/ , do a test and post back here the results url so we can check it better.

Try DKIM... might help...

Sometimes Gmail and Hotmail mark some IP ranges for unknown reasons (most related to previous owners spam reputation), when this happens there is little you can do, however I know of reports that sending email to multiple gmail address and marking the emails as "Not Spam" does help bringing your reputation back up (do this carefully or you might end up in a worse situation).

All mails are marked as spam even in hotmail,Yahoo etc.It happens in all mail


G-mail warning-"Why is this message in Spam? It is in violation of Google's recommended email sender guidelines.  [b]Learn more"[/b]

In mail mail header I find a line "Recived from(ipv6:::1)". Is that a problem?

Please post the result from https://www.mail-tester.com/

Double checked everything about your logs and I could not find anything wrong with your configuration.
From my experience (because I had a similar case recently), it has to do with your IP reputation, probably you are using some provider that is known for spam.

Your email is NOT being marked as spam by everyone, probably just the big players (Google, Microsoft and Yahoo).

Check your IP here: http://www.apews.org/
Result is:
Oooops 104.238.182.138 is currently listed in APEWS :-(
Entry matching your Query: E-180001 104.0.0.0/8
CASE: C-1404 - IP allocations to providers with a bad reputation
Special Reason: No traffic until allocated
History: Entry created 2007-05-28


All other Blacklists are Clean (http://whatismyipaddress.com/blacklist-check) however it might mean that this ip (or ip range) sent spam before it was on your "hands" and that Google marked it and never deleted it.


I wish you good luck, you have a hard road ahead you!!
Easier will be to buy another IP...

Please have a look at this

Fwd/Rev DNS Match - Help No

I have installed sentora in panel.360shutters.in. I have even created reverse dns record as
138.182.238.104.in-addr.arpa name = panel.360shutters.in.
Eventhough i get this error when I check in http://spamcheck.postmarkapp.com/
1.3 RDNS_NONE Delivered to internal network by a host with no rDNS

You are right... That escaped me... I'm sorry!

I'm not an expert on DNS, but if you could change your Rever DNS to 360shutters.in instead of the current one, that might help, but as long as the IP is the same it should be ok.

Check this: http://mxtoolbox.com/domain/360shutters....ndmonitors
Everything, rDNS included, seems to be ok.
Reverse DNS matches here: http://mxtoolbox.com/SuperTool.aspx?acti...n=toolpage
The issues with SOA should never impact Spam filtering.

WARNING: Found mail servers with inconsistent reverse DNS entries. You should fix them if you are using those servers to send email.
Server IP PTR (Reverse) IPs
360shutters.in. 104.238.182.138 <-------------------> 104.238.182.138.panel.360shutters.in. ?

All mail servers should have a reverse DNS (PTR) entry for each IP address (RFC 1912). Missing reverse DNS entries will make many mail servers to reject your e-mails or mark them as SPAM.

All IP's reverse DNS entries should resolve back to IP address (IP → PTR → IP). Many mail servers are configured to reject e-mails from IPs with inconsistent reverse DNS configuration.
