I just worked through the online version of "An Elementary Introduction to the Wolfram Language" with Mathematica running on a Pi Zero W. Amazed to find most things worked on that tiny platform.
There were a few examples of using SendMail in the book that I wasn't able to make work. Yahoo didn't like the mail being relayed through the Wolfram Cloud so I was attempting to configure the SMTP server settings, but can't find the "Preferences > Internet & Mail > Mail Settings" menu suggested by the SendMail::cloudrelay message that appeared in my notebook.
Since it may be important, I am using
pi@raspberrypi:~ $ mathematica --version
Any help getting this set up would be appreciated.
Mail server settings can be specified via SetOptions[SendMail, ...] -- see the documentation page for an example.
Also, the preferences dialog can be opened by evaluating the following in a notebook
Thank you! Used the "PreferencesDialog" as above and managed to get a test email to work.
