It tried to put my surname in the banner image and the image is only applicable to me. This is a typical case of harnessing one-to-one personalized email marketing service. The recipient, of course, will be much impressed.
The good news is that all existing DNS software packages can support additional text strings for implementing SPF. However, receiving mail servers need to be upgraded to perform the SPF interrogation.
Here below is the IP addresses that can be associated with the domain aol.com:
> set type=txt
aol.com text = "v=spf1 ip4:18.104.22.168/24 ip4:22.214.171.124/24 ip4:126.96.36.199/24 ip4:188.8.131.52/23 ip4:184.108.40.206/24 ip4:220.127.116.11/23 ip4:18.104.22.168/24 ptr:mx.aol.com ?all"
aol.com text = "spf2.0/pra ip4:22.214.171.124/24 ip4:126.96.36.199/24 ip4:188.8.131.52/24 ip4:184.108.40.206/23 ip4:220.127.116.11/24 ip4:18.104.22.168/23 ip4:22.214.171.124/24 ptr:mx.aol.com ?all"
Suppose an email has the domain name "example.com" in the "MAIL FROM:" field and the server dsn.rfc-ignorant.org is where we want to lookup. We will look at example.tld.dsn.rfc-ignorant.org, and if the IP address 127.0.0.2 is returned, the domain name "example.com" is blacklisted.
Ha... I have gained some new knowledge in the area of DNSBL.
I tried a work around solution. I started an FTP server (Cerberus) on the PC holding the 5GB files that needed to be transferred out. The other PC run SmartFTP client to download the files. This seemed to be a better solution than sharing folders over the same network segment.
For those that have more than 2 PCs at home, they should have an FTP server to circumvent problem in sharing folders.
SenderBase Network sets up a global email traffic monitoring network. In quantifying email volume, the Richter scale used to measure earthquakes is applied to message volume calculated using a log scale with a base of 10. The maximum theoretical value of the scale is set to 10, which equates to 100% of the world's email message volume (approximately 10 billion messages/day).
By checking the IP address of our company's outgoing mail server, our Richter magnitude is 1.9. This can be translated to 7900 outbound email messages per day. Hey....., this is a rather interesting concept.
There are about 300 tracks in Les Mills Bodycombat (BC) series. I try to list the 10 most favorite tracks. Here is my choice in the order of preference :
Greensleevs : BC19 – 03
Ludwig is alive : BC17 -8
Symphony No. - 8
Razzia : BC18 - 08
Bagpipes : BC26 - 04
Excalibur : BC11 - 5
Guita Damage : BC26 - 02
Stuck on you : BC23 - 01
I like chopping : BC19 - 01
My Sharona : BC10 -5
By the way, some combat fans do not know who Ludwig is. Ludwig is the given name of the famous German musician Beethoven. His full name is Ludwig van Beethoven.
In fact, HKIX provides a looking glass service that we can look for the IP prefixes advertized or received through a particular AS number. "Looking glass" is an interesting term. I am still looking for the exact defintion meaning in the networking world.
