Question: iCloud Email bouncing back when sent from new Macbook
I just installed my time machine back-up into this new Macbook so my iCloud accounts are synched (iPhone & Macbook).
For some reason when I send a message to specific ppl using Mail on my macbook with an iCloud account, the message bounces back and I receive the following:
Status: 5.7.1 (SMTP transmission failure has occurred)
Remote-MTA: dns;mx0.lcn.com (TCP|220.127.116.11|34022|18.104.22.168|25)
(mailguard-scan7.mailguard.com ESMTP CanIt-Appliance)
Diagnostic-code: smtp;554 5.7.1 MailGuard: Message rejected because of
unacceptable content. For help, please quote incident ID 08VBk7uIn.
But when I resend the "same message" with my iPhone the message is received/sent.
Can anyone help me on this one?
