Dealing with Duplicate emails in Postfix

By Jamsi • May 16th, 2008 • Category: Linux

If you’re receiving duplicate emails on your postfix engine, check the mailq and you will probably see error messages which relate to “trace service failed”. It most likely means that your Postfix engine is using an older config file.
Give the following a whirl.
postfix upgrade-configuration
then
/etc/init.d/postfix restart

“The following signatures couldn’t be verified because the public key is not available”
Try
apt-key add /usr/share/keyrings/debian-archive-keyring.gpg
Then

apt-get update
apt-get install package-name

If that doesn’t work, check that you have the debian-archive-keyring package.
apt-get install debian-archive-keyring
