Believe it or not, Tellus doesn't support encryption. https://www.reddit.com/r/canada/comments/464glo/psaif_you_use_a_telus_email_account_telus_does/?st=itb9thrx&sh=2a6ed83e
I think when Google starts to refuse unencrypted email, it would make sense for postfix to bounce them.

I don't block by TLD but I do have a single mail server that breaks the RFC by rejecting any mail not sent via STARTTLS and interestingly is doesn't get much spam at all. Seems a lot of spammers don't bother with TLS while most legitimate mail does. Maybe (for now) that's a better metric? Legitimate mail that doesn't use TLS tends to be blog notifications, for what its worth.
