Email redirects stopped working this week

[#1]

Hi all,

Having trawled the forum, I think this is a (slightly) different problem.

I have been using a handful of redirect for several years of the form name@domain.plus.com which all stopped working on Monday.  I can still use Plusnet Webmail to get into my catchall account and have not received an email from Greenby about migration.  In fact I only learned about the mail migration today.

By deleting the redirects, mails immediately go to my catchall account so I can survive like that but it's not ideal.

I'm redirecting to both an Outlook address and an iCloud address.

Question: does Plusnet still allow redirects or is something else going on?  

Thanks!

Hi @jpwatson 

A warm welcome to the forums.

This is indeed a problem different for the others around here at the moment.  You have not yet received an email from Greenby because your email service is not yet in the frame for moving to Greenby.

Redirection on a single email address can only go to one destination; therefore I infer that address1 redirects to Outlook and address2 redirects to iCloud.

Are you sending to @useraccount.plus.com or to @yourhosted-domain.co.uk ?

Plusnet has not changed its approach to redirects ... but some end receiving services might have done.

PlusNet does not (never has as best as I can recall) support SRS which is essential for maintaining the integrity of SPF validation at the end receiver.  Without SRS, SPF validation checks to see if - the last hop SMTP is deemed valid - for the ORIGIONAL sending domain.  That will assure a SPF validation failure.

However if the originator used BOTH DKIM and SPF anti spam measures, the under a one or the other requirement at the receiving end, emails will be accepted.

I have just ran a number of tests where the redirects go to my Outlook account and another.  They all succeed, even thought they all fail SPF validation ... but given that the sender ALSO DKIM signs the email, they ae accepted at the remote end.

If those sending to you are only doing SPF, you will encounter issues redirecting to some of the recently hardened big bully boy email platforms, such as Outlook, Gmail and iCloud.

Hi @Townman ,

Thanks for the rapid and comprehensive response - you're probably on to something there. 

Yes, you're quite right - I'm redirecting along the lines of:

• my-wife@domain.plus.com to wife@icloud.com
• my-name@domain.plus.com to me@outlook.com

I set up a test redirect and tried various methods that I have available.

• Sending to this test redirect alias from Gmail, corporate O365 and from Plusnet itself (both via Webmail and local mail client) all resulted in a delivered email. 
• Sending to the alias from several personal outlook.com or several icloud accounts failed. 

I can't think of a way to troubleshoot this further without additional information from either the Plusnet end (their support line denied all knowledge and responsibility for the redirect service) or Outlook (good luck with that!) 

Probably time to do what I should have done when I stopped using Plusnet broadband several years ago and migrate everything off this email service alas.

thanks again for your help

I will keep digging on this.

Emails sent from other places to Plusnet, redirected to Outlook appear to be working for me ... however something sent from Outlook to the redirected address give rise to a blocked by policy issue...
