In an effort to reduce the amount spam received by users of the UNC-CH central email system, ITS utilitizes email block lists to block email domains and individual hosts known to be sources of spam from sending messages to @email.unc.edu email addresses. When email messages are sent from these blocked domains or hosts, the messages will be rejected with a 550 Access denied error in the bounced message.
ITS accepts requests for removing email domains or hosts from its email block lists and evaluates the requests on a case-by-case basis. If you suspect an email domain or host from which you normally receive legitimate email has been blocked, indicative from the Access denied error message described above, contact the ITS Response Center at (919) 962-HELP or [ https://www.unc.edu/ar-bin/websub/index.pl ] Submit an Online Help Request to request the block be removed.
Once a request is received, it will be forwarded to the ITS Postmaster staff for evaluation and possible action. Please be sure to keep a copy of the bounced message with the Access denied error. The Postmaster staff might need to review the message before an action can be taken.
If you are an off-campus email provider, you can follow the same steps above to request your email domain or host be unblocked. If you wish to use the [ https://www.unc.edu/ar-bin/websub/index.pl ] Submit an Online Help Request system, click the non-authenticating issues link on the login page.

it would be helpful if this page had an interface that would allow someone to search for a domain name to verify that it has been blocked by the university email servers, along with a reason why.
why does this error come up when i try to send email using a client (Thunderbird) from an airport wifi connection?? i suppose VPN would take care of that...?
