Mail forward postfix

Postfix is a popular open-source mail transfer agent (MTA) that can be used to forward emails. Here are the general steps to set up email forwarding in Postfix:

Step 1: Configure Postfix

First, you need to configure Postfix to forward emails. You can do this by editing the /etc/postfix/main.cf file (the location may vary depending on your system).

Add the following lines to the end of the file:

mydestination = yourdomain.com
myhostname = yourdomain.com

Replace yourdomain.com with your actual domain name.

Step 2: Create a new alias file

Create a new file called /etc/postfix/aliases (the location may vary depending on your system). This file will contain the email forwarding rules.

Add the following line to the file:

[email protected]: [email protected]

Replace [email protected] with the email address you want to forward, and [email protected] with the email address you want to forward to.

Step 3: Reload Postfix

After making changes to the configuration files, you need to reload Postfix to apply the changes. You can do this by running the following command:

sudo postfix reload

Step 4: Test the email forwarding

Send an email to the email address you configured in the aliases file (e.g., [email protected]). The email should be forwarded to the email address specified in the aliases file (e.g., [email protected]).

Additional tips

• Make sure to update the mydestination and myhostname settings in the main.cf file to match your domain name.
• You can add multiple email forwarding rules to the aliases file by separating each rule with a newline character.
• You can also use regular expressions to match email addresses and forward them to multiple destinations.
• If you're using a virtual mail server, you may need to configure the virtual_alias_maps setting in the main.cf file to point to the aliases file.
