Registration mail comes from not existion domain (connect.mozilla.COM)

[SiggiB]

During registration, change of mail account and notification about new post the e-mails sent use a domain that does not exist (connect.mozilla.com). My E-mail Provider is blocking that e-mails (and he is right!).

Can someone have a look at that? connect.mozilla.org works well as it is registered.

Many Thx
