I have three rather pressing questions about exim.
1) How would I create a virtual mailbox - one for a person who doesnt have a user account on my system?
2) My copy of exim is responsible for e-mail going to multiple domains. How can I tell exim which domains users belong to so ericn@??? will work but ericn@??? will return unknown mailbox?
3) In order to be able to send e-mail to other domains, people need to be able to authorize themselves by e-mail address or SMTP authorization. Access by IP is just not an option in this case. How can I create an access list/database of accounts that exim can read from and process using an authenticator, ACL, or whatever?
Ive been trying to get a working setup that meets these requirements for more than a month now and Ive tried sendmail, qmail, and now Im trying exim. Any help would be greatly appreciated.
