If there is a connectivity failure between the SharePoint farm and SMTP server, are outgoing emails stored in a queue in SharePoint until the connectivity is restored? If so, how long that queue is maintained? During the connectivity failure, it gives the following error in the event viewer: Event Type: Error Event Source: Windows SharePoint Services 3 Event Category: E-Mail Event ID: 6857 Date: 1/11/2011 Time: 10:51:50 PM User: N/A Computer: <server name> Description: Cannot connect to SMTP host Is there anyway to figure out the emails which SharePont tried to send during this interval and whether they were delivered?
