Hello Phillip,

I'm not sure if I understood your problem correctly, but I'll try :-) 
See below.

This does not seem to be a dash                  ^^^

I think that could be a character which is not allowed for email 
addresses. It looks like a long hyphen which I get on a german keyboard 
layout with "AltGr + -".

This I understand as the server saying: "don't use '–' (long hyphen) 
but '-' (dash) instead.

Sorry, I don't understand where you get that "–" (long hyphen) from, 
maybe some HTML-formatted emails?!
