[New-bugs-announce] [issue44361] test_smtpnet failed with SMTPServerDisconnected on x86 Gentoo Non-Debug with X 3.10

[STINNER Victor]

New submission from STINNER Victor <vstinner at python.org>:

x86 Gentoo Non-Debug with X 3.10:
https://buildbot.python.org/all/#/builders/698/builds/112

This buildbot worker has Internet connection issues, so my concern is only how test_smtpnet handles Internet issues.

The two tests which fail use "with socket_helper.transient_internet(self.testServer):", but it seems like this context manager doesn't catch SMTPServerDisconnected.

Maybe transient_internet() should be modified to catch smtplib.SMTPServerDisconnected (or even the generic smtplib.SMTPException)?
