Hi Guys,

We developed a issue overnight with out BES server.

Infrastructure info :

BES Version - BES Express 5.0.2.29
Zimbra Server - Release 6.0.7_GA_2473.RHEL5_64_20100616202447 RHEL5_64 NETWORK edition.

Approximately 50 BES users.

The issue is that no one can send mail from their devices.

Receiving mail to the BB device is fine, instant.

Tested sending from the BES Profile in Outlook on the BES server and receive the same error :

From: System Administrator
Undeliverable : ( Whatever the subject of the sent message was )

Your message did not reach some or all of the intended recipients.


Any ideas?
