Receive a Mail Delivery Failed Error When Sending Message to Hotmail or Outlook Mail Accounts

Hosting, Web Wise

Stop SpamThe other day I received a Mail Delivery Failed message from clients that were using Hotmail and Outlook.com email accounts.

The backdoor code in all three plugins works in a very similar way by calling to a remote server and inserting content and links on the affected sites. Experts believe the backdoor code is used to inject hidden SEO spam (cloaked links) on affected sites that help improve the search engine ranking of other sites.

Information about the disk space warning notifications!

Email, Hosting

Although they appear to pop up out of nowhere, a courtesy notification is sent out to our clients if they are reaching their allotted disk space for the hosting account.

This article will help answer what can you do when you receive one? How do you prevent the problem from occurring in the first place?




If it’s the first time you’ve ever gotten the disk space warning message from NWD, it will most likely be warning you that you are using 80% or 90% of your allocated disk space, so your site and email won’t be dead in the water quite yet. The warnings start at 80% and go up to 98%, warning you about disk space.
