Dear All,

We are facing a big issue with Blackberry from last 15 days. issue is blackberry users not able to send mail within the domain each other users , for example.

not able to send mail to same domain user through blackberry. but can send mail to other domain user like gmail.com yahoo.com privatedomain.com etc. user can also send mail to another domain on same server through blackberry.

before 15days every user were able to send/receiving mail each other without any problem, we have also checked on server logs and found users were sending mail to each other until 13th of Nov 2010 after that they user was getting problem.

as per server logs we found blackberry server was using the address
srs.bis.eu.blackberry.com until 13th of Nov after that they have changed the server address to srs.bis7.eu.blackberry.com and users are getting problem.

can you any one give me the solution for resolve this issue.

Waiting for your valuable suggestion.

Regards
Ranjan
