This is a manually created list which might be outdated in some places. In addition, test results may be wrong for various reasons. Please take into account the fact that email providers have to be very cautious when modifying there servers, e.g. to not lock out old clients and to avoid problems when receiving or sending emails.

So, please don't take this list too seriously, and/or try to ...

... understand the test results and the implications they might have:
