Spam filter chaos

Spam filter chaos

Hi.

Like many others, for a few weeks I've been getting mailer daemon generated emails:

SMTP error from remote server for RCPT TO command, host: mx.zohomail.com (165.254.167.50) reason: 541 5.4.1 Mail rejected by destination domain

By your responses to other threads I learnt that this is because Zoho considered the emails as SPAM. By the way, none of the rejected emails were actually SPAM. Even stranger, on two emails sent from the same IP to the same destination with the same subject and text one day and the next, the first one gets trough, the second one is rejected. Luckily I forward email from another server to Zoho and the other provider sends the rejection emails its daemon generates to me, if it wasn't for this I probably woudn't have noticed I'm losing emails.

Rejecting emails that you're not 100% sure that are SPAM is utterly wrong. So:

  1. Are there plans to roll back this change?
  2. Is there any way I can opt out of this and go back to the old behaviour, where I got emails that the system thought were SPAM in the SPAM folder, instead of being rejected?
  3. Alternatively is there any way I can disable SPAM filtering altogether (note that on the control panel - mail administration - org settings I have set Organization Spam Process Type to Off and emails are still being rejected)?
I see for others you seem to be adding some senders or IPs to a whitelist. Don't bother doing that on my case, that's not an acceptable solution to me.
