Sending mail over IPv6? Authenticate!

Josh over at Word to the Wise explains that as Microsoft brings live IPv6 support for its Office365/Exchange Online Protection email platforms, they're mandating that all mail sent over IPv6 must authenticate with either Sender Policy Framework (SPF) or DomainKeys Identified Mail (DKIM). Unauthenticated mail will be rejected. Read more about it here.

Domains clear.net and clearwire.net have been retired

If you're trying to send mail to subscribers at clear.net or clearwire.net today, you'll notice that all delivery attempts are being rejected, because wireless data provider Clearwire has retired all email services as of April 15, 2015.

Once upon a time, Sprint was the biggest investor in Clearwire, and Sprint's 4G data service was provided over the Clear WiMAX network. Sprint fully acquired Clearwire in 2013, and announced that it would be shutting down the Clear network sometime in 2015. It stands to reason that this email domain retirement is likely related to that overall acquisition and service shutdown.

I was not able to find any information related to the transition of clear.net or clearwire.net subscribers to other domains.

Outlook.com Deliverability Support Form

Lots of folks seem to have an outdated bookmark (or have found an outdated link) for the Outlook.com (aka Microsoft Hotmail) deliverability assistance request form.

Here's the correct link (as of June 2015):
https://support.microsoft.com/en-us/getsupport?oaspworkflow=start_1.0.0.0&wfname=capsub&productkey=edfsmsbl3&ccsid=

For information on how to troubleshoot deliverability issues when sending to Outlook.com, visit the Outlook.com Postmaster website. Their Troubleshooting page may be of particular interest.
