XF 1.3 Microsoft is blocking my emails!

    So I recently moved to KH and ever since I've been having multiple emailing issues. Atfirst all my emails sent to gmail and yahoo were getting filtered as spam along with microsoft and aol blocking them completely. On top of that apparently my new server's IPs were on multiple spam blacklists...

    After about a week of wrestling with this issue, we've now resolved all of them except for Microsoft blocking my emails. They've unblocked me multiple times (3), only to reblock me couple days after.

    The error message returned by them is:

    host mx1.hotmail.com []: 550 OU-002 (SNT004-MC4F31) Unfortunately, messages from weren't sent. Please contact your Internet service provider since part of their network is on our block list. You can also refer your provider to http://mail.live.com/mail/troubleshooting.aspx#errors.

    Looking that error up on their site shows:

    Mail rejected by Outlook.com for policy reasons. Reasons for rejection may be related to content with spam-like characteristics or IP/domain reputation. If you are not an email/network admin please contact your Email/Internet Service Provider for help.

    Basically, the issue seems to still revolve around my new server's IPs having a bad reputation because of it's previous owners. What can I do about this? Is it some other problem?

    Maybe your IP is clean but a near IP on the same network segment is spamming like crazy and that's why you're getting filtered...

    When I had this problem years ago I remember I filled a form and then it got solved... but since you said that you have been blocked 3 times I guess you have already filled that form...

    What does the KH support team says about this problem?

    They've mainly tried to play the blame game and put it on my sites. I just keep telling them that it's impossible since I never had the issue on my previous hosting site and that all my sites are forums so I'm not sending spam... It's sooo frustrating...

    I'll ask about the IP segment.

    Do you have SPF and DKIM records for your domain? If so, did you update the IP's in those entries when you changed servers?
    Hotmail and Live seem to be finicky about that. I had some issues with Hotmail rejecting forum email before I set up SPF and DKIM on my domain.

    As @SamL said, you need to make sure that your SPF and DKIM and RDNS are correct. Not only that, the Hotmail rep I talked to said the simple fact of an IP change can cause it to start hitting their filter.

    What's SPF and DKIM and where would we set these records? I've never had a problem but don't know what these mean?

    SPF = Sender Policy Framework http://www.openspf.org/
    DKIM = DomainKeys Identified Mail http://www.dkim.org/

    Both important to prove your mail server is who it says it is.

    I have both setup on the new servers. Funny thing is i didn't have these setup on my old servers and didn't have any issues.

    What can i do about that then? Its been over 2 weeks now on my new server and its still havings issues. Gmail and yahoo filtering my emails as spam did fix itself though.

    Two weeks is no time.. it took me to MONTHS to get it fixed for Hotmail... and that was coming from a clean IP to a clean CIDR.

    What did you do to get it fixed? Just wait for reputation to build?

    You can fill out the MS Sender Information Form to request that they conditionally mitigate by unblocking your IP's. After that, they may set a low limit on sent daily mails until trust builds, but at least it puts you in touch with them directly. They will investigate and provide you with the reasons you are being blocked.

    This is what they replied last time:

    Other then the last two items about joining those two programs, Xenforo's default emails should have no content issues...so there really wasn't much direction there.

    That, and sent them a reply that it was no big deal - that I would just totally disallow the use of any Hotmail/Live/Outlook domain account to be used to register on any of my sites until I could confirm that they were going through and not being marked as spam. :D
    I also have my sender set as do_not_reply for the name.

    Wow, that's big of you. Didn't you lose out on alot of members then?

    Even doing that much it took you months....jeez I can't believe this is such a hassle and somehow I was able to completely avoid this on my last hosting.

    Considering I get very few registrations - nope
    Your reputation with them is probably based on your old IP. Once you got a new IP then it sent up some warning flags with them.

    So it looks like it's Symantec's Brightmail that keeps blocking my server and because Microsoft uses their list I then get blocked by Microsoft's emails.

    I've been unlisted and relisted 3 times now. So I've come up with a new idea. Anyone know what the sql query is to turn off all thread notifications for all user's that have a certain email account (ie: hotmail, outlook, msn, live). Also, what would be the the sql query to turn off all pm notifications with the same requirement on email address.

    I'm thinking of turning these off for awhile so I can build reputation with them then turning them back on.
