A Solution that WORKED for me:
I don't know how my outgoing (smpt) settings got scrambled, but they did. Mail IN was fine but outgoing mail has been problematical and ceased altogether today.
The settings recommended by Telstra did NOT work for me.
The following Account Settings for the Outgoing Server in Mozilla Thunderbird (harvested from the iiNet link in one of the messages above) are:
- Description: smtp
- Server Name: mail.bigpond.com
- Port: 25 [Note that this is nothing like what was recommended]
- Connection security: STARTTLS
- Authentication: No authentication.
I hope it works for you if you still have the problem,
Regards - Rick
