Comment 5 for bug 1897523

Here is my /var/lib/dpkg/info/ssmtp.config file.

set -e

. /usr/share/debconf/confmodule

if [ -f /etc/ssmtp/ssmtp.conf ]
then
        for v in `grep -E "^(root|mailhub|rewriteDomain|hostname|FromLineOverride)=" /etc/ssmtp/ssmtp.conf`
        do
                export $v
        done

        db_set ssmtp/root "$root"
        if [ -n "$mailhub" ]
        then
                if [ `expr index "$mailhub" :` -ne 0 ]
                then
                        db_set ssmtp/port "${mailhub#*:}"
                        db_set ssmtp/mailhub "${mailhub%:*}"
                else
                        db_set ssmtp/port 25
                        db_set ssmtp/mailhub "$mailhub"
                fi
        fi
        if [ -n "$rewriteDomain" ]
        then
                db_set ssmtp/rewritedomain "$rewriteDomain"
        fi
        if [ -n "$hostname" ]
        then
                db_set ssmtp/hostname "$hostname"
        fi
        if [ -n "$FromLineOverride" ]
        then
                if [ "$FromLineOverride" = "YES" ]
                then
                        db_set ssmtp/fromoverride true
                else
                        db_set ssmtp/fromoverride false
                fi
        fi
