SpamExperts Now Available!

While the SpamTitan product has been great to us for the past four and a half years, it has become less effective at filtering out spam and the per email address pricing has always been a concern. Over the past several months, we have been hard at work preparing a better solution for you.

We are very proud to announce that we are now a SpamExperts partner. Not only has our testing shown them to be superior at spam filtering, we’re confident you’ll be pleased with the pricing as well. You no longer have to worry about how many email addresses are on your domain. In place of SpamTitan’s $1.00 per user we’re offering SpamExperts at $2.00 per domain. This has resulted in a significant cost reduction for many of our clients while also offering a better service.

We completed the migration of all SpamTitan users over to SpamExperts early last week and have since opened up the service offering for all clients. A free 30 day trial is available if you would like to give it a try, just submit a ticket to request it. Additional information can be found here.

We have quite a few other ongoing projects currently so stay tuned for more updates!

Updated SPF Requirement

A couple years ago, we published a post on the proper configuration of SPF records when sending emails through our servers. Although not a default configuration, this is very important when you’re enforcing validation of SPF using “-all”. Due to some internal changes, the required entry has changed a little. Previously, you needed to add an A record for spf.gzo.com (+a:spf.gzo.com) and now you’ll need to simply include spf.gzo.com (+include:spf.gzo.com). A screenshot of this entered correctly in cPanel is shown below.

For those with DNS hosted by us, your SPF record has already been updated with this change. If you’re not hosting your DNS with us, the existing A record will continue to function normally in the short term, but please be sure to make the necessary change. If you have any questions or concerns, please submit a ticket and we’ll be happy to assist.

Adding Office 365 DNS Records via WHM or cPanel

Office 365 has quickly become a popular option for clients requiring Exchange hosted email. As a result, we frequently see tickets seeking help with setting up the required DNS records. Even if you’re familiar with editing DNS zones, the required SRV records may throw you off.

Microsoft does provide a general guide for all of the necessary DNS records here but it doesn’t specifically address adding them via WHM or cPanel. If you have WHM access, using the “Edit DNS Zone” link under “DNS Functions” on the left menu will be the easiest option. From there you can add the necessary records at the bottom of the page. You will have to do this in batches since there aren’t enough fields to add all of the records in at once. Once you’re done, the added records should look like this:

You’ll notice we’re using “dathornexample.com” as the domain there. Your own records will instead use your own domain. The “msXXXXXXXX” value is provided by Microsoft to verify your domain, yours will have numbers instead of the placeholder X’s. When editing DNS records via WHM, you should always put quotes around TXT values, as can be seen in the SPF record above. You’ll notice the other “MS=” TXT record doesn’t have quotes shown, that’s because they were automatically removed since they were not needed in that case. With WHM, you’re best off putting quotes around the TXT values and letting WHM decide what to do. Continue reading

SpamTitan & SPF Records

As many of you know, we offer a paid business class spam filtering option called SpamTitan. You may not know, however, that whether or not you pay for inbound SpamTitan filtering all of your outbound email is still filtered by our SpamTitan cluster. If you aren’t familiar with our SpamTitan filtering you can learn more about it or signup for a free trial here.

We began filtering all outbound email through our SpamTitan cluster back in 2012 because we knew how important email delivery was to our clients. Since then we’ve experienced very few issues with our outbound mail IP addresses getting black listed or having a less than excellent reputation.

The vast majority of our outbound spam comes from forwarders that clients have setup to forward their domain’s email to their Gmail or other third party account. The filtering stops a lot of these spam messages from being forwarded and negatively impacting our IP reputation. Occasionally we do also see an email account’s login information having been compromised and used to send spam via SMTP and SpamTitan is able to stop most of these messages from ever leaving our network.
