Data Type: long
Default value is 5. Although the maximum number is unlimited, it is recommended to set the value to 10 - 64. If the specified SMTP server has concurrent connection limit, the MaxThreads should be less than this limit.
How does FastSender work?
FastSender has an inner threading pool based on MaxThreads count. Firstly, Send or SendByPickup submits email to FastSender mail queue. Secondly threading pool retrieves email from mail queue and send it out. Finally OnSent event informs that the email was sent successfully or unsuccessfully.
No. of worker threads in the threading pool of FastSender is automatically adjusted based on the actual usage. The maximum no. of worker threads is up to the value of MaxThread property specified.
