emailQ NET

emailQ.NET is a companion product for Smtp.NET and runs as a Windows Service. emailQ.NET dramatically increases performance by queuing your messages on your hard drive for immediate or scheduled delivery.

It allows you to control the mail sending load of your Windows or ASP.NET applications and get enterprise level performance.

emailQ.NET Features

IIS Integration
Smtp.NET works together with emailQ.NET to create email messages in standard "eml" file format, recognized by IIS Virtural Smtp Server.
The generated "eml" files can be sent directly to the IIS pickup directory or scheduled for future delivery to IIS or sent to another mail server.

Smtp.NET Integration
Most of Smtp.NET's features are supported in the first release of emailQ.NET, including authentication, remote server specification, and failover server specification.
Properties not currently supported for queued messages, but may be supported in future releases:
- TimeoutConnect
- TimeoutGeneral
- ConnectionRetries
- EmailReport
- Port
Multithreading
With emailQ.NET, you specify the maximum number of threads to be allocated for message sending. By default, the maximum number of threads is 20. This is optimal for most systems but can be increased for high end systems.

Scan Frequency
emailQ.NET works by scanning the specified queue directory at the interval specified. By default, the scan frequency is once every 60 seconds.

Windows Service or Application
emailQ.NET runs either as a Windows Service or Windows Application.
- Windows Service - When running as a service, emailQ.NET will work in the background and does not require a user to be logged in. This is optimal for servers that are unattended. Running in this mode also uses less memory and resources.
- Windows Application - When running as an application, emailQ.NET will work in the foreground like a normall Windows Application. When the program is closed, the queue will no longer be scanned and messages will not be delivered. This mode is optimal for Windows 98 and Me, which cannot run programs as a service.
