Troubleshooting connection issues
If automatic mailbox detection fails, contact AdriaHost support and ask for the exact mail server hostname to enter under Advanced settings.
Also check the following:
- that you entered your full email address;
- that your mailbox password is correct;
- that you entered the MCP server address correctly;
- that you restarted Codex when prompted;
- that you completed authentication in the browser window.
Security notice
Enter your mailbox credentials only on the AdriaHost connection page. Do not enter your password in a conversation with an AI assistant, terminal commands, or prompt text.
