We've got a server project that's listening on IMAP connections to proxy messages for many different users accounts. We want to test that server for scalability. To that end, we're setting up an IMAP server with lots of dummy users to generate inbound traffic to our server project.
I'm curious about how to best do that on a Ubuntu server instance and also what the IMAP software would pose the least amount of trouble configuring many users for. Should each our of dummy users have an account on that Ubuntu machine or is that not needed?
