DNSSEC for Primary DNS

Roller Network — Sat, 01 Jun 2013 17:40:41 +0000

We’ve released DNSSEC support for Primary DNS zones. This change marks a major new feature release after several months of work. As this is the initial public release, please let us know if you find any bugs we’ve missed or have any suggestions on how to improve it.

FIX: Multi-Level Forwards to Disabled Mail Boxes

Roller Network — Sat, 11 May 2013 20:17:38 +0000

We added some additional checking in our system to mail forwarding for the case where a forward with an email address destination resolved to another forward to a mail box within the same hosted domain name was disabled. This was observed causing a mail loop for hosted mail domains in some cases. Our fix was to add additional logic to check another level of validity only when a mail domain is in “hosted” mode.

The $1 Fiber Optic Network

Roller Network — Mon, 22 Apr 2013 14:16:22 +0000

The cost of raw Internet bandwidth has plummeted over the last decade, and when you’re Google, it is even cheaper. When Google announced their fiber project, they initially claimed their network would be open to other providers. When Kansas City launched, they quietly retracted that. Even though Google is promising a number of upgrades to iProvo, having a government sanctioned monopoly for $1 is a sweet deal that would have never been offered to a local provider like XMission.

Did you know… only part of “192″ and “172″ are private?

Roller Network — Tue, 05 Mar 2013 18:15:57 +0000

Only a portion of the “172″ and the “192″ address ranges are designated for private use. The remaining addresses are “public,” and routable on the global Internet.

From: https://www.arin.net/knowledge/address_filters.html

In August 2012, ARIN began allocating “172″ address space to internet service, wireless and content providers. There have been reports from the community that many network operators are denying access to devices having IP addresses from within the entire 172 /8 range. As a result, any device with a 172.x.x.x IP address may have difficulty reaching some sites on the global Internet. The only way to solve this problem is for those operators to reconfigure their router or firewall access control and filter only address space from the 172.16.0.0 /12 range.

Network Core MTU Increase

Roller Network — Sun, 03 Mar 2013 01:19:43 +0000

We’re making changes in our network core by changing the MTU to 9216 (from 9000). We don’t anticipate any impact, but as always, contact us if anything seems odd. 9216 is the lowest common denominator MTU across our various routers.

Colocation customers taking advantage of jumbo frame support should continue to use an MTU of 9000 for Ethernet interfaces connected to our infrastructure.

DNSBL Shutdown: NJABL

Roller Network — Fri, 01 Mar 2013 23:35:57 +0000

Effective immediately, Rollernet will discontinue use of the dnsbl.njabl.org DNSBL zone due to its shutdown. We’re also removing it from all custom settings.

Source: http://www.njabl.org/

March 1, 2013: NJABL is in the process of being shut down. The DNSBL zones have been emptied. After “the Internet” has had some time to remove NJABL from server configs, the NS’s will be pointed off into unallocated space to hopefully make the shutdown obvious to those who were slower to notice.

Mail: New Signature Databases

Roller Network — Fri, 22 Feb 2013 23:54:16 +0000

We’ve added the “blurl” and “phishtank” databases to our ClamAV third party databases. For more information see sanesecurity.com (we also donate an rsync mirror to the project).

Mail: SpamAssassin Custom Subject Tag

Roller Network — Fri, 22 Feb 2013 21:48:10 +0000

A new option to customize the subject tag for the SpamAssassin content filter has been added. The default is still “** SPAM:”, but this tag can now be customized with a limited set of ASCII values. These options are now referred to as “subject tagging” whereas they were previously called “subject prepending”.

Mail: ClamAV Tagging Mode

Roller Network — Fri, 22 Feb 2013 21:40:13 +0000

The ClamAV antivirus filter now has an optional tagging mode which will insert the header “X-Rollernet-ClamAV” if a signature match is found. The behavior of the “reject on match” mode is unchanged.

As part of this we’ve added two new rules to SpamAssassin for scoring based on the presence of this header: ROLLERNET_CLAMAV (default score of 10 for matches) or ROLLERNET_CLAMAV_3RDPARTY (default score of 4 for ignored third party matches).

Roundcube Webmail Keyboard Shortcuts

We’ve added a keyboard shortcuts plugin (source) to Roundcube. There’s a help popup that shows the shortcuts: use shortcut ? or click the icon of a keyboard on the message list navigation toolbar. Here’s a list of them as well:
