Hi. Since the Thunderbird update in March/2026, my Bell sympatico.ca email is no longer able to send emails out through Thunderbird. No error messages but emails never get to destination (I tried sending to myself on both gmail and sympatico accounts). I receive emails without issue. I tested the sympatico from the web or my iPhone and it works. Seems something changed in T-bird back in March? I validated the Outgoing SMTP server settings and all seems OK (See attached file for screenshot of settings). Any idea why and what changed to cause this? Tx, Robert Ziwani
