Emails rejected by Plusnet spam filter

Question

Emails rejected by Plusnet spam filter

I use OS X Yosemite Mail as my default email app. I recently tried to email 3 people with Plusnet email addresses. They were short emails, no attachments and each was sent to a single address. I tried both HTML and plain text and tried both my iCloud and Gmail accounts. Every email was rejected by Plusnet's spam filter with the message below. However when I sent the emails from iCloud Mail webpage they got through. The recipients have asked Plusnet for advice but have been told it is an Apple problem. The error message is

Recipient address: xxx@xxx.plus.com

Reason: SMTP transmission failure has occurred

Diagnostic code: smtp;552 Spam Message Rejected

Remote system: dns;mx.avasin.plus.net (TCP|17.172.124.249|57861|212.159.8.200|25) (avasin19.plus.net Plusnet Cloudmark Gateway ESMTP server ready)

I don't want to have to log onto iCloud when Mail ought to be capable of handling all my email. Why is this problem happening and how can it be fixed?

I hope you can help.

Thanks, Fiona

iMac, OS X Yosemite (10.10.3)

Why not set up an iCloud e-mail address. Then you won't have to log in to iCloud. Mail/Preferences/Accounts - click the + at the bottom left and select iCloud.

The Spam flag is not set by Mail, but by the email server. You, or the addressees, need to contact them.

Hi Eric

As mentioned in my original query, I do have an iCloud email address. The problem is that if I send email via Mail it is rejected, however it gets through if I

go via iCloud. The problem is somewhere between Mail and Plusnet. Any other ideas?

Hi Rysz

As I said in the original query, the addressees with Plusnet accounts have all asked Plusnet to let the emails through but Plusnet say the problem lies with Apple's Mail app. Given that emails from my iCloud address do get through when I send them via iCloud, but are rejected when I send them via Mail, it does seem as if the problem lies with Mail. Any ideas?

Hi Eric

Yes, emails sent from my iCloud address via Mail are rejected. Emails sent from the same address via iCloud webpage are accepted.

Sender's email doesn't even have the ability to mark the outgoing messages as spam.

With your iCloud account you can use the same address with .me, .mac and .iCloud. Apple treats all of them as the same email address, but Plusnet might not and is blocking one of them. Confirm the outgoing email addresses used when you're on web vs. when you use Mail app.

Hi Rysz

I use my .iCloud address in both Mail and web. I have also tried my gmail address in both Mail and gmail's web. Whichever address I use, it is accepted by Plusnet when it comes from the relevant web provider, but is rejected when it comes via the Mail app. I have also asked the addressees to email me first so I can reply to them, but that doesn't work either.

It seems as if something in the way in which Mail handles the messages triggers a rejection at Plusnet. Plusnet blame Apple (of course) and I imagine Apple will blame Plusnet if they ever bother to reply to the query. I would like to know if anyone else has encountered the problem and found a workaround, but if not I will just have to faff around using the web mail instead.

Hi,

> Diagnostic code: smtp;552 Spam Message Rejected

> Remote system: dns;mx.avasin.plus.net (TCP|17.172.124.249|57861|212.159.8.200|25) (avasin19.plus.net Plusnet Cloudmark Gateway ESMTP server ready)

Despite what you've may have been told, the above error indicates that our inbound mail server has rejected the message based on either it's origin (i.e. the server it's been sent from), or the content of the message itself.

It would be helpful if you could send one of the messages that's being rejected to a non-Plusnet hosted email address, and then provide our support team with the full headers and content of the received message. This allows us to check both the content of the email and the route it's taken which might give us a clue as to where the problem lies.

I don't mind taking a look for you if you can provide me with a support ticket reference or similar.

Cheers,

Hi Bob

That's very helpful, thank you. I am not a Plusnet customer, so I don't know how I can get a ticket to access your support team. Can you help or do I need to go through someone with a Plusnet account?
