For each e-mail address, you can set up different "aliases". These are e-mail adresses that point to the same mailbox. In other words, an alias is an e-mail address of which e-mail is delivered in your mailbox.

An example: John has an e-mail address john@mycompany.com but is also responsible for the sales in his company, that's why he has created an alias sales@mycompany.com which is linked to e-mail address john@mycompany.com.
This way, John will receive mails for both john@mycompany.com and sales@mycompany.com.

If you have e-mail addresses with your Kinamo hosting, you have an unlimited number of e-mail aliases.
