Advanced sending options

The ColdFusion implementation of SMTP mail uses a spooled architecture. When an application page processes a cfmail tag, the messages that are generated are not sent immediately. Instead, they are spooled to disk and processed in the background. This architecture has two advantages:

• End users of your application are not required to wait for SMTP processing to complete before a page returns to them. This design is especially useful when a user action causes more than a handful of messages to be sent.
• Messages sent using cfmail are delivered reliably, even in the presence of unanticipated events like power outages or server crashes.

You can set how frequently ColdFusion MX checks for spooled mail on messages on the Mail/Mail Logging page of the ColdFusion MX Administrator Server tab. (The default interval is 60 seconds.) If ColdFusion is extremely busy or has a large existing queue of messages, however, delivery can occur after the spool interval.
