Problem

JIRA e-mail notifications doesn't display the sender name.
The 'from' field only displays the account used by JIRA and there are no errors in the logs.

Cause

This may be caused by a transport rule in Microsoft Exchange 2003 and 2007.

Resolution

Contact your infrastructure network administrator and review you Exchange Server configurations. A transport rule may be set up for JIRA's IP address, making the wrong name display.
