I'm having a problem with sending e-mails off of Outlook. The issue is, certain customized email address associated to Symantec keep getting bounced back for over a week now. We've checked out IP on your blacklist tool remover, and it said our IP wasn't associated to any blacklist, yet we still cannot send emails out.
The error from emails bouncing back is:
host cluster1a.us.messagelabs.com [85.158.139.103]
SMTP error from remote mail server after RCPT
Our IP Address is: 198.57.193.16
Is there any way we can be removed? Thanks in advance.
