Hi!
I still need help
I tried to use ethereal.email as a SMTP server.
Because I need my own domain to register on the smtp2go, I don't have it.
Tell me please, can use ethereal.email as a SMTP server?
Or do I need my own DOMAIN name?
Maybe there's a solution to my problem on the guithub?
For example, a solution related to a SMTP server

Below is the error in the terminal window:

You're getting the SMTPSenderRefused message, which means the server did not like the sender's address.

https://docs.python.org/3/library/smtplib.html#smtplib.SMTPSenderRefused

Given the documentation on Ethereal, it looks like you need to use your ethereal email address as the sender; and given they want to cut down on spam, they are most likely checking your senders address and noting it does not match their domain.

This actually looks similar to this issue #8. See the comment here that describes the problem: #8 (comment)

Are you able to use a sender's address that has a valid mx record (i.e. your personal email address)? If so, you can try creating a dummy account on gmail to see if you're able to send mails from that address.

Lately, some of these SMTP providers are implementing stricter measures to thwarts educational tools like this library.
