Did a search and found nothing pertinent to this question...
I have a 7290, Cellular One is the carrier. I work for a school district (the only one on campus using a blackberry btw) and the email medium is Exchange 2000. I currently use BIS.
I am able to receive all email regardless of domain. When I go to send emails to other school district employees (ergo the same domain name) it gets kicked back and the following mail delivery failure error...
The following message to <someone@school-domain> was undeliverable. |
The reason for the problem:
5.1.0 - Unknown address error 550-'<me@school-domain>: Sender address rejected: Blocked'
I had my IT department white list blackberry.com, .net and all of the 5 smtp servers that Blackberry has for North America. I still get the same delivery errors.
My questions is 2 fold...
1) Has anyone ever experienced this problem (and if so - any resolution)?
2) Is BIS the right process for what I need? Should the school be using BES? I know BES express is free (which will appeal to the administration) and has 1 license with it - would this work?
At my previous job - I used a blackberry for my email (smtp and pop3) and it worked great. I (and my IT dept) cant seem to get passed this problem with the BIS and they have no experience with BES.
Any help is appreciated!
