This question already has an answer here:

Ok, i've been seeing this the last week, tought it could be gone in a few days by itself, since i wasn't blacklisted and my DNS entries are all ok, but when i try to send e-mails to some user at Outlook, Live or Hotmail, i get this:

2015-02-11 14:54:58 1YLaYz-0000IT-I1 H=localhost.localdomain (higipel.com.br) [127.0.0.1]:41242 Warning: "SpamAssassin as cpaneleximscanner detected OUTGOING smtp message as NOT spam (-1.0)"

2015-02-11 14:55:01 1YLaYz-0000IT-I1 Completed

And the weird thing is, i have a few hundred domains under 3-4 IP's at most, but just 4-5 domains are presenting this 'problem'

Anyone found a solution for this yet?

    Did you look in "Junk"? – Michael Hampton Feb 11 '15 at 17:16
  • Yes, several times, even a day after i sent the test e-mail, not even a clue of the e-mail in there. :/ – Jorge Ferrari Feb 11 '15 at 17:19

    The solution is to boycott these providers. They talk about free market, let's do it. (When I know of a solution, I'm sure I'll post it here) – sebix Feb 12 '15 at 17:04

    @JorgeFerrari Do you have SPF and DKIM in place? – sebix Feb 15 '15 at 9:37

It's because of Microsoft's SmartScreen.

You gotta be in concordance with these topics:

  • Setup a SPF record
  • Setup DKIM
  • Setup a DMARC record
  • Setup a reverse DNS record
  • HELO must be a host name not an IP
  • Make sure that your IP is not on a blacklist
  • Use a static IP address for your server
  • Sign up for JMRP and SNDS

I've followed this article, which solved the same problem you're having.
