My email has suddenly stopped sending emails in Thunderbird. I get the error: Sending of the message failed. An error occurred while sending mail: Outgoing server (SMTP) error. The server responded: Cannot connect to SMTP server 211.29.132.250 (211.29.132.250:587), connect error 10060.

Have reinstalled Thunderbird, disabled AVG Antivirus, disabled my Asus router's firewalls and contacted my ISP (Optus) who say there's no issue on their end. I can send emails through their email based website. I can ping via Command Prompt no problem

Any advice will be appreciated

  1. Is the server identified in your account settings as mail.optusnet.com.au? It is rather odd that the error mentions the IP address if your settings use the correct server name.
  2. Is the connection security set to None as designated by Optus. (Rather odd for a company that has already been hacked to be enforcing plain text communications, even in their own network.)
  3. Are you connecting to the mail server using an Optus internet connection?

Note: Reinstalling Thunderbird is almost certainly not going to work as the issue is in communications with the server (it is timing out) not in the installation on your device.

Unfortunately I feel Optus support is about as poor as that offered by Telstra (I am about done with them). Neither appear to offer folk that actually know anything about email.
