I cannot get Thunderbird to work as I want. I have three email addresses: [edited] @gmail.com (private), [edited] @aafishburn.com (website and business) and fallback [edited] @myisp.net.au. I wish to use Thunderbird for the Website/Business emails, i.e., contact@aafishburn.com. It will not work. It sends error "Cannot connect to server" or similar and will not process the emails. Outlook and Gmail do, but that is not what I want. Can this be fixed? Website is https://aafishburn.com How can I set it up so it sends and receives emails to and from [edited] @aafishburn.com, please.
