That is the entire problem in itself. You can only connect to smtp.telus.net without any connection security from a Telus IP. If you're using a VPN, you need to use the secure smtp settings to send. I've had no issues with Thunderbird on MacOS with the correct settings in it.
Server: smtp.telus.net
Port: 1025
Security: STARTTLS <<< Important. If SSL/TLS is selected, you will get a connection error.

Community Power UserWhen you use Webmail you are connected to the Telus servers for SMTP/IMAP/POP and thus don't have the issue. This is mentioned in the link I sent previously:
Note: Some countries may block these settings. If they are not working in the country you are in, you will have to use webmail.telus.net from any device.
You say you are using port 587 for SMTP. The link I sent says to use port 1025 and SSL. You will need to authenticate when connecting to that port (supply you Telus email credentials).

Community Power UserFurther to the comments of FuzzyLogic , when you use your Telus assigned IP address, you are internal to Telus’ network, and can use an unsecured SMTP login on port 465 or 587, however, since your packets on VPN travel outside Telus’ secured network, you need to authenticate as though you were travelling internationally. Thus the link to the mobile device instructions, and port 1024 plus SSL.
