Linux Mail Server Setup and Howto Guide

Hi na,

If you don't see the message, MailScanner is probably not scanning your emails. Check the following

1. Did you disable the Postfix service? MailScanner should be the one to launch Postfix.

2. In your main.cf, do you have the line

header_checks = regexp:/etc/postfix/header_checks

and in your /etc/postfix/header_checks the line
/^Received:/ HOLD

Those settings causes Postfix to place incoming mail into the holding area where MailScanner will
scan it and place it into the incoming queue. Otherwise, mails will go directly to the incoming queue
bypassing MailScanner.

Try to check if mails are really going to /var/spool/postfix/hold. Stop MailScanner and start Postfix. You should no longer be receiving mails because the mails are getting trapped in /var/spool/postfix/hold. If you still receive mails, there's your problem.

Another possible reason for those missing message is when you turned it off. See Add a Disclaimer to Outgoing Postfix Emails.

The problem is in Postfix, it is not storing mails into the holding area. Double check your main.cf and header_checks, you need to configure Postfix to store mails into the holding area.
