All mail goes to spam

[apinto]

I will reply with quotes from previous posts of this thread.

(...)

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).

Like I've told you on my first reply, Gmail (and hotmail, yahoo etc) use a different spam blacklist (you can't check it) and they also blacklist some IP ranges or ISPs.

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...

This is probably the issue, I'm almost sure of it.
Try with another IP if you can.

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

I do not think this might be the issue, however it can be, seems it is not yet fixed.
