If i have a dynamic ip address can i use ZxMail to collect emails and distribute it to my users?
Yes you can, you can mirror your own domain, if you mirror your own domain ZxMail can fetch emails sent to your ISP or domain hoster and redistribute to a specific user, or if your hosting domain allows a catch all mailbox (mailbox that accepts all emails no matter the user part) then you can redistribute it to your domain users, look at the sharing option in creating an external mailbox.
