We recently had a virus/spyware issue on our network that caused us to get listed on a few spam blacklists. We've gotten ourselves removed, and rectified the virus issue, but vzw.blackberry.net and sprint.blackberry.net still seem to be blocking our emails.
Doing a telnet to port 25 at any of their mail servers just seems to reject our connection attempt. Testing with telnet from outside our network works fine. For example, doing a telnet to mx01.bis.na.blackberry.com our connection immediately gets dropped. If testing this from outside our network, I get a response from their mail server.
I've sent an email to postmaster@<hidden> and abuse@<hidden>, but no response yet and our connections are still being blocked after over 24 hours.
Any idea if there's a particular procedure in place that I should be following?
Any idea how Blackberry determines who and what to block?
Thanks in advance...
