mail slurper-mysql-auto deletion of emails

[jveerapandian]

Hi,

Sometimes, we notice that with latest version of mail slurper, the emails are getting purged automatically(with mysql db) everyday morning.
There's reboot of the sandbox every day morning and we assume that because of that the data is not persisted.
With sqllite this behavior is expected but the same issue started happening with mysql database as well. Ideally as per the mail slurper official page, the mysql db configuration should act as a persistant store and emails should be retained.
Is there any known workaround for this?

Thank you.
