When you sign up on ezip you choose an ezipcode and a username. Just like you use a telephone number to call a friend, or a zipcode (or post code) to send a letter through the mail, an ezipcode is a number that identifies a group on ezip.
An ezip group can have one or more members in it and each member will have a username. To send a message to someone on ezip you use the form username@<ezipcode>.
To receive email from someone not on ezip use the form username@<ezipcode>.ezip.email or username@<ezipcode>.ezipcodes.com
As an example, let's say your ezipcode is 1234 and your username is megamind. Other ezip users can chat with you using the address megamind@1234 and you can receive legacy email at the address firstname.lastname@example.org and email@example.com
All ezipcodes will have a page in the ezip directory. The page can be used to give information about the group, give links to other webpages associated with the group and more.
Directory pages can be password protected if desired.
An example of an ezip directory page can be found at http://100.ezipcodes.com
When you chat with other ezip users, you can use channels to organize your conversations. You can also use channels to organize your email messages. When you prefix your ezip email address with a channel name, the message will appear in that channel. For example, email sent to firstname.lastname@example.org will appear in the bills channel (you don't need to create the channel beforehand).
One of the most important features of ezip is a rich set of security settings that allows you to control who is allowed to send you messages.
You can set the security policy for messages from other ezip users on each channel as follows:
- Only allow/deny messages from specific ezip users
- Only allow/deny messages from users in the same ezipcode
- Only allow/deny messages from users in specific ezipcodes
- Require unknown ezip users to ask permission before messaging
Along with security controls for ezip messages, you can set security policy for incoming email as well.
- Only allow/deny email from specific email addresses
- Only allow/deny messages from users in specific email address domains
- Require unknown addresses to answer a challenge
- Require a secret keyword in the text of the message
- Quarantine all unknown addresses until manually approved
