re: Turned off antivirus and firewall.

If your Anti-Virus product also managed your Firewall eg: Norton (NIS) It is possible the default Firewall is now functioning and could also be blocking Thunderbird. But it is not really a good idea to have both of these switched off. So just switch it all back on and make sure Thunderbird is an allowed program.

What Anti-Virus' are you using?

Close Thunderbird. Access the Firewall and make sure 'Thunderbird' is allowed. If it is already set to allow, then block it, ok it, access again and reset to 'Allow'.

Restart Thunderbird.

In 'Account Settings' window click on 'Outgoing Server (SMTP)' How many outgoing servers are listed? It is usual to have one per mail account. select the one which contains the 'User Name' = mail account email address. click on 'Edit' 'Description' is something you can use to help to idenitfy which server is which. Type something to help identify that mail account eg: Personal - Work - Your NAME in capitals. etc 'Server Name' : mail.orcon.net.nz 'Connection Security' : STARTTLS (This will auto change port to 587) 'Authentication method' : Normal Pasword 'User Name': full email address click on OK

Then make sure the mail account is using that outgoing server. In left Pane select the mail account name bottom right you will see 'Outgoing server (SMTP)' - make sure you have selected the correct outgoing server - you will see the 'Description'. when all is correct, click on OK. example images to help clarify what I'm talking about.

Confirm when you have double checked all the above. '
