No, it's not limited to HPO, and this is very important to performance. - Use SMTP_FORWARD in "go.user" (Windows may vary) to define a number of connections and mail server. I use 8. - Use MAXBSMTP to increase the size of mail bundles, not exceeding the limit of your SMTP system. I use 250. - Newer versions of Listserv probably have settings and features of which I have yet to learn!
