Since February this year, I cannot send any emails from my Thunderbird account which has an optus.net.com account. I receive the emails but when I try to send an email, a box appears with the message 'failed. Recipient address rejected due to domain discourages use of this host.'

I can send emails with optus address on my phone and other devices, but not using Thunderbird on my PC. I have contacted Aussie broadband which are my server provider who believe the issue is with Thunderbird. I have also contacted Optus who agreed that the issue is with Thunderbird.

I can send emails from Thunderbird which use aussiebb.com.au. I was able to send emails from optus.net.com prior to Feb 2025. I would appreciate talking to someone to help me solve this issue. Thanks, Louise.
