How do I correct all the email failures

I'm getting tons of failures so I tried using my Proton Mail account after Gmail but it still has problems.

I guess with Gmail it's smtp issues? Proton I'm not sure.

I'm also not sure where I should start looking.

Any suggestions greatly appreciated.

The screenshot shows that your node runs into a timeout when connecting to remote smtp-servers on port 25.
Since it's both gmail and protonmail (and I don't expect both of them to be really down) - my guess is that your ISP is blocking connections from your link on port 25 (many do to prevent outgoing spam).

Options you have:
* ask your ISP if this is the case and what they suggest in those situations (usually they do offer a smarthost through which you can relay mail
* configure SMTPAUTH for the accounts and send the mail on port 587 (submission) - there's many howtos in the internet for those configuration

I hope this helps!
