Hello postfix list! I've recently checked the gmail bulk mail guidelines, and I've seen that they recommend this header in the email: "Precedence: bulk"
The source is this URL: https://mail.google.com/support/bin/answer.py?answer=81126#format We have a designed our own mail server for clients alerts and updates, and I'd like to implement this, however, I've no idea how to make the server to add that header in each mail that it send. Googling fo a while, but all I found is how to add the header in telnet or sendmail command line, and I'd like to add it when it hits the email server, or before sending the email. That would be awesome! Do you have any links or tips? Don0t have a clue how to do this. Thanks! Cheers, Martin
