I am using Thunderbird on 3 computers and 4 OS. Windows 10 Pro 64 bit, Windows 7 Ultimate 64 bit, Linux Mint 17.3 64 bit, & Linux Mint 18.0 64 bit. When all were upgraded to 45.5.1, all of my outgoing email is showing up as SPAM. The same problem is occurring on every OS listed. Prior to this upgrade, all outgoing email came back normal, not as SPAM

Restart Thunderbird with add-ons disabled (Thunderbird Safe Mode). On the Help menu, click on "Restart with Add-ons Disabled".

If Thunderbird works like normal, there is an Add-on or Theme interfering with normal operations. You will need to re-enable add-ons one at a time until you locate the offender.
