Windows – Improving IIS SMTP performance

iissmtpwindows

Currently IIS is sending about 60k emails an hour.

Is this a good number?

How fast can IIS send?

Are there any good ways to increase speed?

Are there good alternatives for running on Windows?

Best Answer

What do you want to do...

Send 60k emails in a shorter batch?
Send more then 60k emails per hour?
Send 60k emails but use less resources?

Generally, any 3rd party software still has to put the emails over the network. The IIS SMTP server is good enough... if it's not, you need a specialist solution/server/OS...
