We moved our DNS servers several weeks ago, but apparently one of the OpenDNS servers had the wrong information cached. This was rectified a couple of days ago, which is why we are seeing these problems today.  Now, there are several senders that still have bad DNS information cached.  If you are not receiving messages from some senders, be sure to notify them that they need to update their DNS cache.

Here is how the sender can find out if their cache is bad:

The sender’s system administrator needs to do a lookup on their mail server to see what IP address they’re getting for our gateway. Additionally, it would be helpful if they could get us the nameserver records they’re seeing for ijnet.net as well.

Examples:

On windows:

nslookup -type=a g1.ijnet.net
nslookup -type=ns ijnet.net

On linux:

dig g1.ijnet.net a
dig ijnet.net ns

Our correct IP’s are:

MF1 – 216.246.89.41

MF2 – 216.246.89.42

G1 – 216.246.89.40

G2 – 216.246.89.37

Having been in the antispam business for a little over four years, we have become very familiar with the various and numerous methods by which spammers try to foil email security systems.  With this key industry knowledge, we believe that we have been given the opportunity to be of service such as few others can.

Over the next couple of weeks, you will see us roll out a new set of services that will allow our customers to promote their services to our enormous database of email addresses.  Due to our understanding of antispam techniques, we will be able to guarantee virtually 100% delivery, thusly increasing your sales.

We know this is an extremely abrupt shift in business practices, but in these rough economic times, we need to take it where we can get it.

Please watch this blog for additional announcements in the near future.

The database maintenance for MF1 and MF2 is complete, and normal mail flow has resumed.  We apologize for any inconvenience.

We need to run a database check on MF1 and MF2 today.  This may cause some messages to be delayed, but no mail will be lost.

We will post again when this is completed.

We have noticed intermittent delays in the receipt of email for some of our customers.  We are working with MailFoundry to fix this issue, and we have also been made aware of a system update that MailFoundry is going to release soon to address this problem.

Keep an eye out for our new podcast, which will be posted later today.
