The mail has come from a subdomain.
For instance, their main Web domain is eonnext.com. So the main website for logging into E.On Next to service your account would be
www.eonnect.com.
Mail originating or sent via that domain would go to @eonnext.com, as in hi, unhappy, CEO, etc.
This forum is on a subdomain, called community, hence the Web address is
www.community.eonnext.com.
The prefix m is usually used for a mobile version of a website. When you go to any website, the server usually gets information on what browser you are using and what operating system. If the server detects you are using a browser on a phone, then instead of connecting you to the regular website (
www.eonnext.com), it will point your browser at the 'mobile optimised' version of the website (
www.m.eonnext.com).
Email can also be associated with different subdomains, although this is not that common. So, an email address or link from m.eonnext.com just means it's from the mobile subdomain.
The mail was 100% legitimate....it was access to their website from Apple devices that was the problem.
You probably ended up getting a blank page for the same reason that folks couldn't log in yesterday from iPhone, Mac or iPad...the site wasn't working for Apple users.
