Setting Up the Database
The database for Warm Mail is fairly simple because it doesn’t actually store any of the
emails.
You need to store users of the system. For each user, you need to store the following
fields:
n
n
n
n
username—The user’s preferred username for Warm Mail
password—The user’s preferred password for Warm Mail
address—The user’s preferred email address, which will appear in the From field
of emails he sends from the system
displayname—The “human-readable” name that the user would like displayed in
emails from him to others
You also need to store each account that users would like to check with the system. For
each account, you need to store the following information:
n username—The Warm Mail user who this account belongs to.
n server—The machine on which the account resides; for example, localhost,
mail.tangledweb.com.au, or another domain.
n port—The port to connect to when using this account. Usually, it is 110 for
POP3 servers and 143 for IMAP servers.
n type—The protocol used to connect to this server, either POP3 or IMAP.
n remoteuser—The username for connecting to the mail server.
n remotepassword—The password for connecting to the mail server.
n accountid—A unique key for identifying accounts.
