SPAM Issues

[#1]

Hi All.

A friend has been unable to successfully send emails to my Plusnet email account because they are rejected by the Plusnet server as being spam - see below (email addresses and subject redacted):

===============================================================================================

Subject:     Message Delivery Failure
Date:     Wed, 11 Oct 2023 08:52:37 -0700
From:     mailer-daemon@secureserver.net
To:     xsenderx@dd.co.uk


This is an automatically generated Delivery Status Notification.
Delivery to the following recipients failed permanently:

* xmex@dd.me.uk

Reason: There was an error while attempting to deliver your message with [Subject: "Re: < subject here >"] to xmex@dd.me.uk. MTA p3plwbeout25-01.prod.phx3.secureserver.net received this response from the destination host IP - 212.159.8.200 - 552 , 552 Spam Message Rejected .

===============================================================================================

I have got the Plusnet spam filter active ever since it was offered after the Plusnet issues with Spam emails many years ago.  It occurs to me that I very rarely receive any emails with the "[-SPAM-]" added to the email subject.  The help mentions getting emails stating that emails have been quarantined but I have never seen such an email.

Note that I use Gmail to access my email using IMAP.  I do reasonably regularly get emails marked as spam by Gmail.

So my questions are:

1. Why am I not receiving the emails?
2. Why do I so rarely get any emails with "[-SPAM-]" added to the subject?
3. Why don't I get any emails saying an email has been quarantined?
4. Why are there no emails at all in my webmail Junk folder?
5. How do I remedy this?

Thanks for any help.

There could be quite a lot of factors, is your friend using his own domain, is the provider known for spamming etc?

Thanks for the response. The answers are yes and no.

Since the post, I have disabled the Plusnet spam filtering; the emails are no longer rejected and I now receive the emails.

What I still don't understand is why I was not getting any emails notifying me that suspected spam mail has been quarantined

The only time you would get notification of 'quarantined' messages is if the Cloudmark system couldn't decide if they were spam - based on the algorithms it uses - others do not generate a notification.

Ok, but why have I never received such a notification?

And i thought that spam messages were meant to end up in my "Junk" folder but there is nothing there?

You have never received a notification because the messages did not fit the criteria for one to be sent.

Where messages end up depends on how you have set up the mail filtering - For almost as long as I've used  Plusnet mail, I have had all filters disabled, and use a third-party program to filter.

Notification / being marked [SPAM] / being discarded all depends on the multitude of spam setting options.  You have only commented that you switched off spam filtering; you did not detail what the settings were, so it is not possible to answer why you have not seen the behaviour you expected.
