SMTP service not running - Event 6599 (SharePoint 2010 Products)
Applies to: SharePoint Server 2010, SharePoint Foundation 2010
Alert Name: SMTP service is not running
Event ID: 6599
Summary: Microsoft SharePoint 2010 Products sends alerts and other SharePoint 2010 Products administration messages by using a Simple Mail Transfer Protocol (SMTP) mail server. When SharePoint 2010 Products is configured to receive incoming e-mail, the SMTP service delivers e-mail messages to a drop folder. A SharePoint timer job scans the drop folder and inserts the messages into SharePoint lists.
Symptoms: One or more of the following symptoms might appear:
SharePoint 2010 Products does not receive incoming e-mail.
Some front-end Web servers receive incoming e-mail while others do not.
This event appears in the event log: Event ID: 6599 Description: there was an error connecting to the Windows SMTP service.
Cause: Automatic configuration for incoming e-mail is enabled and the Windows SMTP service is not installed on one or multiple servers, or the Windows SMTP service is not running on one or multiple servers.
The SMTP server is not installed by default. SMTP can be added by using the Features Summary area of Server Manager in Windows Server 2008 R2.
