Joplin Server Mail issue

Hi all

Many thanks to the team for bringing Joplin server to us. Excellent.

I have installed it and already have 4 users using it, all able to synced their client apps etc. not tried the collaboration bit yet but will soon.

What I have noticed as the admin, is that the mail section doesn’t works. The system doesn’t email users password requests or opening of new accounts etc.

Has anyone had any experience of this issue and able to offer any guidance.

Again great work and thank you very much.
