forward emails to non existing accounts to one central one in Postfix

Hi ThoreTheWookie,

What you are looking for is setting up a catchall mailbox.

With a catchall mailbox, all your e-mails will be redirected to one account. Some websites send confirmation e-mail messages to the e-mail account you use to register. In this case, using a catchall would be the best option.

Let’s set a catchall Postfix mailbox then

• Edit /etc/postfix/virtual and configure your catch-all address like below.

@example.com myuser

• Let’s say you don’t want all mails to be forwarded to this catchall mailbox. You can add exceptions so that you can use the accounts normally.Add them also in /etc/postfix/virtual file. The below configuration will send all emails to user “myuser” except emails of DO@example.com and test@example.com.

@example.com myuser
DO@example.com  info
test@example.com support

• Save /etc/postfix/virtual file and execute the following command.

postmap /etc/postfix/virtual

• Now to update the Postfix’s configuration file - /etc/postfix/main.cf

virtual_alias_maps = hash:/etc/postfix/virtual

• After the change has been saved, you’ll need to reload the Postfix configuration. To do so, execute:

service postfix reload

Now you have a catchall mailbox configured.

Kind regards, Kalin D.
