Emails to specific domain are bounced

I'm new to smartermail and net to email servers at all.

Can anybody explain why this email is bounced? Do I need to make any changes in our mail server?

Hi Penko. I believe this is happening because it is using the command "HLO" instead of an "EHLO/HELO". It looks like an issue with Icewarp. Please see the following link for more details... http://forum.icewarp.com/forum/showthread.php?2467-Problems-with-emails-from-icloud.com-apple
