Problems receiving "delivery receipt emails" after moving mail from Exchange to Offsite Pop for Spam filtering Max Points for Solution
Posted on 2007-08-02
I recently switched from Exchange and moved our mail offsite to a Pop mail system. Our Pop mail now goes through a Spam Filter mail server. I can send an email from this pop account to another one I have not being filtered and receive message. When I click yes on the return delivery receipt message. I get this error message.
"The message could not be sent because one of the recipients was rejected by the server. The rejected e-mail address was 'firstname.lastname@example.org'. Subject 'Read: Testing Delivery Receipt 5', Account: 'mail.spamfiltered.com', Server: 'mail.nonspamfiltered.com', Protocol: SMTP, Server Response: '550 not local host spamfiltered.com, not a gateway', Port: 25, Secure(SSL): No, Server Error: 550, Error Number: 0x800CCC79"
Using SSL on the spamfilter account for incoming (995) and outgoing (465) servers.
The company hosting our mail server and doing spam filter told me to use these settings but says the
delivery receipts are a client problem, any help would be great.
