MAS o Menos

In an effort to thwart SPAM, many DNS Blacklists have surfaced. They supposedly track which servers are sending SPAM. Email programs or mail servers then check these lists before delivering email to the user. When their right, they are great. When then wrong, it sucks.

After an email address is wrongly accused of SPAM, it’s up to them to correct the issue one list at a time. And there is no guarantee that you can ever clear your good name. This domain, which doesn’t even have a newsletter or any public email activity is on two blacklists.

CriticalMAS is on the Realtime Blackhole List. According to this Polish site:

The decision of blocking any mail from you is up to recipient of your mail. I’m the recipient in this case. It’s my server, and my RBL.

CriticalMAS is also on the Blars Block List. This site states:

The BlarsBL is maintained by Blars at his wim.

If you would like a site be added or removed from BlarsBL, you may hire Blars at his normal consulting rates (currently $250/hour, 2 hour minimum, $1000 deposit due in advance for non-established customers) to investigate your evidence about the site. If it is found that the entry was a mistake, no charge will be made and the entire deposit will be refunded.

In the end I don’t give a damn if I can’t receive email from some people in Poland or customers of an extortionist. I tested a few other domains of friends and saw alarming patterns. Mail hosts need to be aware of these rogue blacklists before they start protecting their customers from SPAM.
