Re: Mail being bounced even though Mailbox exists, bounce message

“Hi. This is the qmail-send program at server.mailserver.com.
I’m afraid I wasn’t able to deliver your message to the following addresses.
This is a permanent error; I’ve given up. Sorry it didn’t work out.”

Take a look in the mail log file:

tail -1500 /usr/local/psa/var/log/maillog

You see errors such as this:

Unable to stat entry '/usr/local/psa/handlers/info'

To resolve you need to remove and rebuil all mail handlers as follows:

1. Stop the mail service

    # /usr/local/psa/admin/sbin/mailmng --stop-service

    OR

    # service qmail stop

2. Backup old handlers in a temporary directory

    # mkdir /usr/local/temp

    # cp -a /usr/local/psa/handlers/before-* /usr/local/temp/

    # cp -a /usr/local/psa/handlers/info /usr/local/temp/

3. Remove the handlers

    # rm -rf /usr/local/psa/handlers/before-*/*

    # rm -rf /usr/local/psa/handlers/info/*

4. Recreate handlers using mchk utility

    # /usr/local/psa/admin/sbin/mchk --with-spam

5. Start mail service:

    # /usr/local/psa/admin/sbin/mailmng --start-service

    OR 

    service qmail start

This may take a little time however it will resolve all errors.
