Please first read Postfix documentation on virtual aliases.
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
Address tags as an alternative
Postfix supports address tags - i.e. address+tag@example.com will end up at address@example.com. This is configured by default and the (configurable) separator is set to +.
For more info, see How to use Address Tagging (user+tag@example.com) with Postfix.
Note that if you do decide to change the configurable separator, you must add the same line to both config/postfix-main.cf and config/dovecot.cf, because Dovecot is acting as the delivery agent. For example, to switch to -, add
recipient_delimiter = -
