    Hello,

    Are you getting the following error from your qmail-smtpd?

    421 unable to read controls (#4.3.0)

    First, check the permissions on the cdb rules file listed (blue) in your smtpd run script:

    exec /usr/local/bin/softlimit -m 30000000 \
    /usr/local/bin/tcpserver -v -H -R -l "$LOCAL" -x /etc/tcprules.d/qmail-smtpd.cdb -c "$MAXSMTPD" \

    Then check your /var/qmail./control directory and files within it for both permissions issues and missing files.

    If neither of these are the problem what other changes have you made? Was this source used on another server? Which patches have you added? Are the dependencies for those patches installed on the new server? There are a variety of patches that could require mysql support such as valid recipient patches and other smtp time features.
