sometimes doesn't recover from network errors on Linux #215
Description
I'm using the proxy as a systemd service, and if I, for example, unplug my router, then I get:
Dec 15 23:13:17 rent python3[481687]: Email OAuth 2.0 Proxy: Caught network error in IMAP server at [::]:1993 (unsecured) proxying outlook.office365.com:993 (SSL/TLS) - is there a network connection? Error type
<class 'socket.gaierror'> with message: [Errno -2] Name or service not known
That's fine, of course, but the proxy never recovers from this state when networking is up again. I have to restart it.
