#1) Every email client I'm familiar with lets you create amultiple accounts. The specifics depend on which client you're using, but look for "Accounts" in the options. But what good do other peoples account on your client? Everybody will be able to see everybody elses email.
#2) There are a number of free email servers available, if your server doesn't have one installed already. If you want to stay in the
Java space, then there's Jakarta James. But didn't you say you wrote an email
client? I must be missing something.
I'll move this to the General Computing forum; please find the
thread there and continue the discussion.
