Dovecot Imap proxy - proxy

Can anyone give me a config example files for dovecot imap and pop3 proxy. Basically it should lookup the username in mysql and get the host server to proxy to. I tried the docs but they were too old.

Effectively bypass chatgpt cloudflare by using different proxy package or different cloud service provider in restricted countries

I have an account in chatgpt but as I located in the restricted country, I tried to use AWS proxy (US server) to login chatgpt. Few weeks ago it worked but now I get an error message access denied error code 1020. I used tinyproxy in stealth mode at first but since I was unable to pass through the cloudflare, I guessed probably the proxy was not good enough to disguise itself as a proxy, so I tried squid vpn in stealth mode and algo vpn, but all did not work(Tried other AWS countries server as well other than US). Until now, I figure out chatgpt might probably just banned all connection from amazon or perhaps my proxy is just not smart enough to pass through cloudflare? What are more options? Any recommended free vpn proxy that I could installed into my AWS EC2 or perhaps I should try other less known cloud services instead? e.g. (other non-restricted country's local cloud services) Besides, I have consider using other free proxy from the internet but as I need to login my gmail, is it danger to do so but since its https so my username and password should be encrypted?
I have the same problem, simple ssh tunneling works you can use a jump server to bypass your country first and than use different server to use as proxy because some of your vps servers get banned with IP, so you may have to use another vpn with different proxy
ssh -D "port to make SOCKS 5 Connection like" <10808> -J <"user">#<"jump server IP"> <"user">#<"final server IP">
than you can use "foxyproxy" extention to build SOCKS5 proxy that uses specified port in this example 10808 to route your browser terrafic through tunnel in port 10808 to final server
or you can use something like sshuttle, but i was fine with this simple tunneling method in GFW

OPENVPN and proxychain (multi proxy servers)

I have a problem encoding the OPENVPN config file. I would be grateful if you could advise me.
when we use openvpn via one proxy we can use this command:
http-proxy PROXY-IP PROXY-PORT auto
USERNAME
PASSWORD
How to change the above code so that when the connection to the first proxy server is established, it is established to the second proxy server (and to the end in a certain number) and finally to the main vpn server?
thank you for your attention

Re-resolve remote AD's ip address when using OpenLDAP as proxy to AD

It is working when setting up OpenLDAP as proxy to AD. However after certain time, the OpenLdap proxy is unable to reach AD unless OpenLdap proxy is restarted.
I suspect that OpenLdap proxy caches remote LDAP IP address, and could not reach AD once IP is changed or AD is under round robin schedule.
Is there a way to force Open Ldap proxy to re-resolve remote AD naming?

windows SDK socket use IE proxy setting to connect internet

I have a C\S program that the client use HTTP proxy server to connect server. We ask the user to input the proxy server IP address, port, the username, and password. Then use Authorization: Basic method to connect server.
But now we want to auto detect IE proxy server settings, and use the IE proxy settings to connect our server. We can get the IE proxy server IP address and port from the registry, but can't get the username and password. So how to use the IE proxy setting to connect internet? (Maybe I should use Authorization: Negotiate to connect HTTP proxy server.)
Many other software has this feature:

SMTP tunnel forwarding

I will like to know if there is any SMTP tunnel that you can setup to run on localhost:25 and have it forward mails to Amazon SES (TLS/SMTPS) using a username and password that you specify in the SMTP tunnel settings.
My problem is that I have an old program that I want to move over to Amazon EC2 and I want it to use Amazon SES as SMTP. But it only allows me to change the SMTPServerName setting. The username and password are empty and cannot be changed.
This user documentation will help you.
