Re: Sending to Office 365 from System i broke

Follow-up to this for the archives: with greatly appreciated help from
Brad Stone, I was able to produce a log showing that the IP address of my
System i was being blocked by Microsoft. They found that my IP address was
being blocked by Spamhaus.org, which they use for filtering.

I did have this IP whitelisted in my Office 365 setup, so not sure why
their Spamhuas check took precedence, but I was able to get the IP
unblocked and everything is rosy now.

Thanks

My SMTP settings:

Mail Router = *none
Firewall = *no
Forwarding mailhub server = *none

Reading through your article:

Step 1: Contact your email administrator: I opened a support ticket with
Office 365 and Microsoft has informed me that it's not a problem on their
side. They're asking me to send them detailed screenshots of the IBM
configuration. I doubt they would even know what they're looking at.

Step: Get a Trace - I'm working on this now.

Hi, Bob.

There are a few more details needed, such as what are your settings in the
CHGSMTPA command for Mail Router, Firewall and Forwarding Hub server. But,
I wrote an article on tracking down email issues on the IBM i since we deal
with this issue a lot with our MAILTOOL software:

http://fieldexit.com/forum/display?threadid=140

What I find interesting in your case is that only one type of account
isn't receiving the email. So, that means that if you're using a mail
router, you'll want to contact the admin to see the logs of the actual
delivery from the router to the outlook account.

If you're not using a mail router, then you should contact the people who
put your email package together to see if they can provide a log to see the
communications between your IBM i and the recipient.

You could also get this trace with our MAILTOOL software as outlined in
the article above.

I have a report distribution utility that sends email from the System
i using the SNDSMTPEMM command. As of yesterday afternoon, the emails
are no longer being received in our Office 365 inboxes.

According to the job logs, the reports are being generated and sent to
the outq that's being monitored.

The email utility sees the reports and is successfully sending the
emails
- everything looks fine.

This setup has been working for over a year. I am a one man shop and
I can say with complete certainty that absolutely nothing has changed
on our side.

So, did something change on Microsoft's side? I have looked in the
spam quarantine and our reports aren't there. I can't find any
evidence that Office 365 is even receiving them.

A possible clue is that I can send successfully to my personal Gmail
account, but not my Hotmail account.

Anyone else running into this same issue? I believe that something
was changed yesterday afternoon in Office 365 to break this.
