How Do I Get PN To Stop Blocking An Email Sender?

[#1]

Hi,
Someone from a company I subscribe to cannot send me emails as PN keeps blocking them.
How can I get PN to allow their emails to reach me?
Thanks

Hi bazzer,
You could try adding the e-mail address in question to the whitelist on the Spam Filter?
You can do that by at http://portal.plus.net > selecting 'Manage My Mail' > 'Spam' > add the e-mail address to the 'Approved List'.

Thanks Chris, I'll try that.
Incidentally the rejection message states "The following organization rejected your message: mx.avasin.plus.net" if that helps explain further?

No problem.
If those steps don't resolve the issue, I would recommend raising a Support Ticket at http://contactus.plus.net and pasting in the e-mail with full headers. Instructions on how to obtain the headers can be found here: http://www.plus.net/support/email/email_troubleshooting/obtaining_headers.shtml
