As of this morning, I cannot use Thunderbird to connect through IMAP or POP3: attempting to do so produces an error message saying that “the connection was refused.”
I have tried troubleshooting already:
• IMAP access is enabled for my account in the Zoho mail web client (and POP3 for my other account).
• Login credentials are correct: I can indeed access my e-mail account through the web interface.
• All port and server settings are correct—and are unchanged from what was working before this morning.
• In Thunderbird, for this Zoho mail account, I have changed max connections to account to 1.
• I have exited Thunderbird, flushed my DNS resolver cache, and restarted Thunderbird.
• I have rebooted my computer.
• I have tried removing the account from Thunderbird and adding it back using the correct credentials and settings.
Even so, I cannot access my e-mail account over IMAP (or my other e-mail account over POP3) through Thunderbird. Has my ability to do so been disabled for some reason?
This happened before, about six months ago, and was resolved after I brought up the issue in these forums. Being unable to access mail through Thunderbird severely hampers my ability to do my job. Could someone take a look at this please?
