Emails being delivered with a empty body

Hi, has anybody has experienced an issue with running erpnext on Ubuntu 18.04 with empty emails?

Email is correctly being delivered, however automatic reports, password reset and even manual emails with a footer have an empty body?

I believed it could be a problem with mail service as it blocks HTML as we are running O365, however empty emails are also being delivered to Gmail

Same observation here Email sent from ERPNext arrive with no message body
