I have been running MIAB for a few years. I am learning Python recently and trying to test a snip of email related code. What surprised me is that I can just send and receive without any user/pass authentication. Is this a normal behavior with any mail server setup, like gmail, etc ?
It can not send email to other domains and it prompts “relay denied”.
It doesn’t work with sender email from other domains.
It only work between local domain for both sender and receiver.
Should I worry about this being used by remote parties? Thanks!
s = smtplib.SMTP(‘box.abc.com’)
