Is this error caused by my smtp or the recipient's server?

When I send an email I get Error 500: 5.2.0 RlwfkTzDowsS5Kfqh: spam detected.
What is the cause (what server said so)? Is it on my end or theirs?

Hello.
Can't reproduce. Check logs and your smtp configs.

After verifications it seems my outgoing email was blocked as spam at the smtp level. Maybe that notification could be made easier to understand for the end-users for example putting 'SMTP:' before the error.

Sometimes that happens. It is because of the smtp server filter configs. If this is your own smtp server just check it's filter configs. If not, check one more time recommended configs for smtp. Also, you can contact with smtp server support team. If this will not help, maybe you need to change smtp.

Yeah I've dealt with the situation, thanks for the tips.
