I have been running linux the last 7 years, but what is new to me is my new setup of a local mailserver. I used the great howto regarding postfix/virtual users (stored in mysql) with a vmail user (/home/vmail/...) (I run Ubuntu 7.10)
I feel I do not understand where what is stored and why... (= meaning I would like to better understand the setup)
The setup works, meaning I can log in and so. So here are some more specific questions:
1. How are the local users related to the virtual, meaning postmaster = root , then root = MyUserNameOnLinux. Is the mails then stored in my home folder or under /home/vmail/MyUserNameOnLinux? Also I have setup my mail adress as a virtual user = email@example.com
. Is this 2 seperate places for mail to be stored?
2. I have my server at home on a DSL connection. Use ZoneEdit for making sure that my hostnames point to my current IP. Up till now I have used fetchmail to download my mails from my ISP. Where will/should fetchmail store the mails? (under MyUserOnLinux or on my virtual user?). Also Would it be easy / better to skip this step and tell ZoneEdit to push the mail directly to my server? (is it possible/recommended on a dsl connection?)
3. Secure backup and restoration of my mail accounts. When I understand the answer on question 1 this may not be an issue. But how can I create a backup of all mails stored on my server, and how easy will it be to restore the backup.
Think this is all for now... hope I will reach a better understanding soon
