nabladesign.com domain discontinued

Tags:

Rhombic Networks changed it’s name from Nabla Design in fall of 2005. We’re lapsing our use of this domain name in 2008.

We’ve made void all nameservers and DNS records. If you were using the nabladesign.com domain, any of your services depending on it (such as DNS, e-mail, etc) will soon stop working.

If you need any help transitioning over to the new domains please contact us.

Our RoundCube Mail installation had severely decayed in the past few months, but we are are now running an up-to-date version that should rectify problems you may have been experienced in the past. Please try it and let us know if there are any problems.

Network connectivity problems earlier this afternoon

Tags: •

Sender Policy Framework implemented as anti-spam countermeasure

Tags: •  •  • 

Rhombic Networks’ e-mail servers now check for valid SPF (more information at the OpenSPF website and Sender Policy Framework Wikipedia entry) records before incoming e-mail messages are received. This may reduce the number of messages that end up in your spam folder, making it easy to check your spam folder for false positives. This is a continuation of the many other ways Rhombic Networks’ reduces e-mail spam.

We have been doing this for several years, but implemented differently. Previously, messages that fail the SPF check may have been marked as spam and placed into your “Spam” folder. Now, if a message fails the SPF check, it will be rejected from Rhombic Networks’ servers, and you will not see it.

If you think you’re losing any mail, please contact support with specific details about from whom we may be rejecting mail destined for you.

SSL certificates refreshed for my.rhombic.net and secure.rhombic.net

Tags:

The SSL certificates for the domains my.rhombic.net and secure.rhombic.net now have new SSL certificates. You should accept them if your browser asks you to accept these new certificates whenever you use services at either of these domains, such as webmail, billing, and database administration.

Tags: • 

For about an hour earlier this evening the authentication system for IMAP and SMTP connections was malfunctioning. You may have received a “Login failed” error during this time when trying to receive or send mail via Rhombic Networks servers. The problem is now fixed.

There should have been no mail loss associated with this event.
