server.load:iNotes - only sending to mail1 User instead of all? Webmail workload won't send at all

We’ve set up an iNotes workload (iNotes6) in server.load to run against our R8 server, but it only chooses to mail to Mail1 instead of spreading out the mail to all users.We tried using a local NAB but with identical results. Has anyone run into this or knows how the script picks mail recipients during a workload test?

We tried to run the Web Mail Workload instead, it seems to run without errors, but even though the mail is reported to be sent in the script log window, no mail is ever routed on the server.

Thanks for any advice

Steve
