Can 2-3 mails per post cause that much stress?

JMail is not limited in any way of how manby concurrent calls it can handle. How ever the threading model of your component may impact the behaviour of JMail.

If JMail behaves slow it's because it does realtime SMTP comunication to your server.

A good thing to speedup jmail is to reuse th object without setting the "serverAddress" property. This cases Jmail to pool the smtp connection and makes it perform alot better under heavy loads.

Also with ASPQMail there is an option for deferred processing, but it did not work, actually it sent the message immediately and the timeframe reached 38 sec, 34s and 34 sec in three consequitive tests. So I assume it is ASPMAIL not ASPQMAIL that is running or it is not correctly setup.

It is installed by default when you install aspemail, but it only runs for 30 days if it is the free version.

It seems to me, if you are willing to throw away email erro processing JMail has an asynchronous mode (or something similar) where control returns immediately to the asp code. If that's so, perhaps that will work for you.

Also, the not free JMail has a process where you can put your mail list in a DB file, pass the db table to JMail, and go on about your business while it sends to all the recipients in background.
