Getting this error when attempting to execute and send a report

I’m not sure as to how exactly the smtp hostname is supposed to be configured. I have it currently set as smtp.gmail.com, but I do not know if this is correct. Do I have to specify a specific email such as yahoo, gmail, etc or can I simply have mail.

I’ve tried an alternate configuration with just smtp.mail.com and received this error instead:

It would be your email provider. The server with the authority to send to the world using your “From” address. The details are provider specific.
See this comment:

Port 25 doesn’t work with smtp.gmail.com. Check the gmail docs at https://support.google.com/a/answer/176600?hl=en – you need either port 465 or 587, depending on if you’re using SSL or TLS
