One of the options to configure auto responder with Postfix
1. Edit Postfix Virtual Configuration:
Open and edit the Postfix virtual configuration file.
Add the following line, replacing email_address with the address you want to configure for autoresponding, and email_address@autoreply.nic.net.sa with the destination address for autoresponses:
email_address recepient_lists, email_address@autoreply.nic.net.sa
For example:
wordpress@example.com recepient1@example.com, wordpress@google.com@autoreply.example.com
2. Edit the Transport Configuration:
Open the transport configuration file and add the following line:
autoreply.domain.com autoreply:
For example:
autoreply.example.com autoreply:
3. Create a Pipe for the Autoresponder in master.cf:
To execute the autoresponder script, create a pipe in the master.cf configuration. Open the master.cf file and add the following lines:
autoreply unix - n n - - pipe
flags= user=nobody argv=/usr/local/bin/autoreply $sender $recipient
4. Create the Autoresponder Script:
Create the autoresponder script at the specified location, in this case, /usr/local/bin/autoreply.
Here’s an example of what the script could look like:
/usr/sbin/sendmail -oi -t << EOF
From: nobody@example.com
To: $1
Subject: Auto Response from example.com
Content-Type: text/plain; charset=utf-8 This is an autoreponder email.
EOF
Customize the script with the appropriate sender address, subject, and content for your auto responses.
There are alternative methods for setting up autoresponders, such as using tools like Procmail, depending on your mail server setup. Postfix provides flexibility, and you can choose the method that best suits your needs.
