Allow users to create email accounts

Hey guys!

So, I have an interesting question! I would love it for my users on my multisite network to be able to create a free email account on my domain from within wordpress.

Now, I know normally this wouldn’t be possible but then I found this

This appears to be exactly what I was looking for yet this plugin has not been updated in 2 years so I am sure its not reliable now.

I was wondering if anyone out there knows of another solution that will allow users in my network to do this? I found this but not sure if it does the same thing as well from the front end.

Thanks for any help or suggestions you can provide!
