Email deliverability problems to Windows Live users

In recent months, we have found that emails sent to @hotmail, @live and @outlook are not being delivered properly.

We have confirmed that the problem lies with how Microsoft is handling their spam filtering; all emails sent from our servers to @hotmail, @live and @outlook email users are being sent properly and our mail logs show that the emails are being received by Microsoft’s servers.

Windows Live Email ServicesWhile Microsoft relies on various authentication filters to determine if an email is spam or not, all of our servers meet their criteria – all email services include the use of SPF Validation, Sender ID Validation and DKIM (1024-bit keys) signatures.

We have also been fielding reports of non-customers having this problem so we are confident that this problem is not related to our mail servers’ reputation or standing.

The Solution?

We have found that @hotmail, @live, @outlook, @mts.net or @mymts.net email accounts will recognize and accept emails sent from an email address listed as a contact.

If you are trying to contact us from an @hotmail, @live, @outlook, @mts.net or @mymts.net email account, you must first save our email address as a valid contact for our responses to make it to your inbox.

More Data Transfer

We’re happy to announce that we’ve increased the monthly data transfer rate on all packages by 5 times!

Now our smallest package (the Starter Package) includes a minimum data transfer limit of 50 GB, while our Business Package allows for 500 GB monthly data transfer.

Minor Updates

Last night, we made several minor updates.

We updated Roundcube Webmail making it a better Webmail service with dozens of fixes for a variety of browsers. We also improved the spam filter which was already blocking out 99.8% of spam.

We updated MySQL to version 5.5.28, strengthened database security, and updated phpMyAdmin (database management) to version 3.5.3.

PHP & MySQL Upgrade

We have a scheduled maintenance window on the evening of Wednesday, December 12, 2012 beginning at 10:00 PM PST.

We will be updating our servers to PHP 5.3.19 and MySQL 5.5 on all servers. There may be intermittent connectivity problems with some databases during this scheduled maintenance window which should not last longer than one hour.
