Q8320010: I'm using 2 SMTP channels now. Can I add more SMTP channels?
By default, the maximum number of SMTP channels is set to 4. To increase this number, change the following registry key: HKLM\Software\ActiveXperts\SMS Messaging Server\Performance\ThreadsSmtp. Please note that the engine will consume more resources when this number is increased, because it needs to create additional threads to handle these channels.(viewed: 1837)
