I have managed to configure the 'email-oauth2-proxy' software to function with Google Mail and Microsoft Office 365, utilizing the IMAP protocol. I am currently experiencing trouble with Google's POP3 protocol.

$ cat /etc/email-oauth2-proxy/settings.cfg

[emailproxy] delete_account_token_on_password_error = True encrypt_client_secret_on_first_use = False allow_catch_all_accounts = True

[IMAP-2993] server_address = imap.gmail.com server_port = 993

[POP-2995] server_address = pop3.gmail.com server_port = 995

[SMTP-2465] server_address = smtp.gmail.com server_port = 465

[@] redirect_uri = https://localhost/email-oauth2-proxy-authorize/ redirect_listen_address = http://127.0.0.1:8801/ token_url = https://oauth2.googleapis.com/token oauth2_scope = https://mail.google.com/ client_id = CLIENT_ID client_secret = CLIENT_SECRET permission_url = https://accounts.google.com/o/oauth2/auth

When I test with Thunderbird email software, I am getting the following error message below.

Jun 12 16:35:03 senhasegura email-oauth2-proxy - b7ce08ef9513[1375]: Caught asyncore info message in POP server at localhost:2995 (unsecured) proxying pop3.gmail.com:995 (SSL/TLS) - error : uncaptured python exception, closing channel <main.OAuth2Proxy listening localhost:2995 at 0x7f2eded0b810> (<class 'socket.gaierror'>:[Errno -2] Name does not resolve [/usr/local/lib/python3.11/asyncore.py|read|88] [/usr/local/lib/python3.11/asyncore.py|handle_read_event|419] [/email-oauth2-proxy/emailproxy.py|handle_accept|1651] [/email-oauth2-proxy/emailproxy.py|handle_accepted|1662] [/email-oauth2-proxy/emailproxy.py|init|1462] [/email-oauth2-proxy/emailproxy.py|init|1305] [/usr/local/lib/python3.11/asyncore.py|connect|336])

I've made a number of changes to the software's configuration file and unfortunately I'm still unsuccessful. Any idea what could be wrong in the config file?

best regards,

What version of the proxy are you using? (python emailproxy.py --version)

The error is not one I've seen before, but I suspect this is something to do with IPv4 vs. IPv6 binding. It is worth trying specifying a local_address value (see the documentation) – for example, 127.0.0.1 or ::1.

What version of the proxy are you using? (python emailproxy.py --version) version = '2022-12-23' # ISO 8601 (YYYY-MM-DD)

cat /etc/senhasegura/email-oauth2-proxy/settings.cfg

[POP-2995] local_address = 127.0.0.1 server_address = pop3.gmail.com server_port = 995

[SMTP-2465] local_address = 127.0.0.1 server_address = smtp.gmail.com server_port = 465

I made the changes and the problem remains the same.

best regards,

Please could you post the full proxy log that includes this error message? (in --debug mode)

I found the error. I was using 'pop3.gmail.com' instead of 'pop.gmail.com'.

Now, I have another problem with the pop3, message attachment file. error.txt

Please upgrade to the latest version of the proxy and try again?

I'm going to assume that this is now resolved, but please feel free to re-open if that is not the case.
