When I send emails, they are bouncing back from certain addresses. All of the sudden even my address is bouncing. So I can't even send an email to myself and some others at my company. I haven't changed any of my preferences or anything. When I view the reporting it says Bounce Code 550...Any ideas why this would be happening? See image below.

Thank you for the update. I have an email scheduled to go out tonight, so I will let you know how it goes. Some template tests that I sent out just a few days ago (well past Jan 28th), were going into Spam folders of the recipients. Hopefully everything is resolved now though...Thank you for the assistance.

Please refer to the following kb article:
it would not be unusual for test emails sent within your own company to hit spam folders - email filters may well pick up a conflict between your domain and Swiftpage server IP addresses.
The SPF Record section of the above kb is useful as are sites like

I was poring over the Bounce Report for one of my customers and see some SPF rejections. We do in fact have the SPF record defined by KB 36812 entered into the DNS system.
But one address stands out: 188.8.131.52
The Bounce report lists this particular IP as being a problem IP address very often. It is the same IP address shown in the first email in this thread posted by OP.
The SPF record provided by swiftpage that we currently have on the domain is:
v=spf1 a mx ip4:184.108.40.206/26 ip4:220.127.116.11/24 ~all
As you can see, the .140 address falls outside these bounds.
Please confirm if the swiftpage server is potentially sending from this IP as well, and perhaps update the SPF KB article to accommodate it? Thanks!

Thank you for the inquiry regarding SPF and the IP range associated with the KB article.
The IP range for 18.104.22.168/24 does cover the 140 address. "~ all" includes 22.214.171.124 ~ 126.96.36.199.
I can see where the confusion lies within the "/24" piece of the range. This is a prefix length of the subnet mask.

With relation to the bounce code for your client, I can take a deeper dive into this if I have the domain name for which they use for their sender profile.
