Last night we fixed the problem where certain domains could not view their mailbox using Mobile Email on their mobile device. These included ix.netcom.com and a few other non-earthlink domains used by our customers. Users reported that when they log in, their messages were not shown. If you log in with those accounts now, the mailbox contents will appear the same as seen in regular Web Mail.
This problem was discovered due to feedback here. Please continue to report any problems.
Other than that we haven't seen any major problems with the launch, so in a week or so our monthly eLink newsletter will mention Mobile Email and encourage all users to try it.
