Seemingly suddenly I cannot send email using Thunderbird. There have been no recent configurational changes. There are several computers in the home. I can log onto these and send email. The issue appears to be localized to my desktop. I can send/receive email from my desktop using Gmail directly, but when using Thunderbird sending (SMTP server) times out.

Solved. Changed smtp (Connection Security) parameter from 'SSL/TLS' to 'StartTLS', and all appears to be well. For all the pain and suffering searching for resolution, this was infuriatingly simple. The VPN support staff was super in helping troubleshoot.

Follow-up... I have cascading routers configured. Primary (ISP provided) router and secondary (VPN) router. Thunderbird is able to send email when logged into the primary router. However, unable to send email when logged into the secondary router. Could my VPN be disrupting communication to SMTP?
