Emails rejected by blackberry servers

[Budi Febrianto]

Hi,

Many users in my office forward their email office to their blackberry
email address like noname at nosubdomain.blackberry.com.
This already running for years without any big problem.

Last night, I found out that all emails to blackberry.com are rejected,
with error message
"550 #5.7.1 Your access to submit messages to this e-mail system has been
rejected."

After googled, I found out that this happen because mostly that my office
domain are listed is one or two dnsbl, that's why blackberry rejected the
emails.

Is someone know which dnsbl that blackberry using?

Checked with http://www.mxtoolbox.com, my domain listed only in INPS_DE, I
want to make sure because INPS_DE want some fee for delisting.

Best Regards
