I have a daily scheduled task running which (some days) sends emails using Gmail SMTP. It last worked on December 24:th, but today it does not. Between then and now it has not attempted to send emails.
On:
server = smtplib.SMTP(smtp_server, port)
I get:
OSError: [Errno 101] Network is unreachable
On the page SMTP for free users I read that:
However, we have to hard-code the IP addresses of Google's servers into our firewall, and these sometimes change, which means that, on occasion, Google may switch to a new Gmail server which we don't know about, and that would temporarily block email until we are able to update the firewall.
Is this what has happened in this case?
