Test: Get the smtp test server using os.getenv() (#117979)

diegorusso · ambv · web-flow · commit 8e36cb7bb2a6 · 2024-04-17T15:31:48.000+02:00
The smtp test server can be set via CPYTHON_TEST_SMTP_SERVER environment variable.
If not set, it uses the default value smtp.gmail.com
This is needed because the network I'm on filters access to
smtp.gmail.com resulting in a failing test.
