Please first read [Postfix documentation on virtual aliases](http://www.postfix.org/VIRTUAL_README.html#virtual_alias).
### Configuring aliases
Aliases are managed in `config/postfix-virtual.cf`.
An alias is a full email address that will be:
* delivered to an existing account in `config/postfix-accounts.cf`
* redirected to one or more other email addresses
Alias and target are space separated.
Example:
# Alias to existing account
alias1@domain.tld user1@domain.tld
# Forward to external email address
alias2@domain.tld external@gmail.com
### Configuring regexp aliases
Additional regexp aliases can be configured by placing them into `config/postfix-regexp.cf`. The regexp aliases get evaluated after the virtual aliases (postfix-virtual.cf). For example, the following `config/postfix-regexp.cf` causes all email to "test" users to be delivered to qa@example.com:
```
/^test[0-9][0-9]*@example.com/ qa@example.com
```
