SMTP Service Error with TB 102.9 on Mac OS 10.15

After updating from TB 102.7.0 to TB 102.9.0 on my Mac OS 10.15.7, I cannot send mail on one of my mail accounts and getting the following message: "Sending of the message failed. The message could not be sent because the connection to Outgoing server (SMTP) smtphm.sympatico.ca was lost in the middle of the transaction." With the previous versions of TB, I did not have any issue with this problem. The settings of this SMTP server is: Port 587, Connection Security SSL/TLS, Authentication method = Normal password. These settings worked perfectly in the previous version of TB! Any suggestions? Thanks.

Yes, effectively changing the security to STARTTLS solves the issue. I note the added clarification on the support.bell.ca which was not so detailled a year ago when I created my account! Thanks for your help :)

Does it work if the security is STARTTLS, the standard for port 587?
