 We see this all of the time — business owners who have been using free email addresses at domains like comcast.net, aol.com, gmail.com, hotmail.com, yahoo.com, etc., who want to start using their own domain name for email (e.g. switching from “dr_fred@aol.com” to “fred@the-doctor-is-in.com”).
While such a change is very desirable for many reasons, people are often uncertain as to how to make the change efficiently and at at the same time not lose any important business email.
This article covers common questions and solutions for making such a move.

Update – April, 2012. openssl v1.0.1 is out and it supports TLS v1.1 and v1.2 which help mitigate this attack. All web sites hosted by LuxSci now use this updated software and are safer. LuxSci recommends using a web host which supports TLS v1.1 and v1.2 for secure web connections.

SSL v3 and TLS v1 are subject to a serious exploit, according to a recently published attack mechanism (called BEAST). This sounds foundation-shattering and kind of scary. When people see this, as when we did, the first panicky questions that arise are:
- What is really affected?
- How serious is it?
- What can I do to protect myself?
- How does the BEAST attack actually work?
After researching this issue, we have digested what we have found and produced this article to answer all of these questions for you.

 We are observing growing numbers of users trying to send legitimate email messages only to be blocked because the IP address that they are getting from their Internet Service Provider (ISP) for their personal computer is on some major blacklist, like SpamHaus. Comcast, for example, has been the focus of many of these issues lately. This message blocking often happens even if a user is sending outbound email through a legitimate email provider like LuxSci.
Users invariably ask:
- Why is the mail blocked even though I am sending through LuxSci or some other email provider and not directly from my ISP?
- What can I do about it?
Fortunately, there is a good reason why the blocks occur and an easy solution to them … with LuxSci’s anonymous SMTP service.
