The file /var/lib/dpkg/info/ssmtp.config contains the following lines:

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

So it was reading your /etc/ssmtp/ssmtp.conf and found something that could not be exported.
