iCloud Mail
Since yesterday, I rec'd the text message from all my customers, vendors and friends said they don't rec'd my reply on their email. Then I found that all the emails I sent out through the iCloud.com outgoing server cannot deliveried. When I change the outgoing server to hotmail.com, then they rec'd it without problems.
Can anyone help on to fix this problem?
