Using GMAIL to send mail with the Mail Action 1.9.0.b5

Yes. Also the subdirectories. In both directories.

systemctl stop openhab2
rm -rf /var/lib/openhab2/tmp/*
rm -rf /var/lib/openhab2/cache/*
rm /var/lib/openhab2/config/org/openhab/mail.config
systemctl start openhab2
tail -f /var/log/openhab2/openhab.log -f /var/log/openhab2/events.log

careful with rm -rf ! :slight_smile: (better use rm -ri to see what you are deleting)
