Only mail sent directly to or from our servers will be authorised. The DMARK error is as a result of Non TalkTalk addresses trying to send through our servers.&nbsp;</P> <P>&nbsp;</P> <P>Ady</P> Fri, 31 Jan 2025 14:50:12 GMT Ady-TalkTalk 2025-01-31T14:50:12Z https://community.talktalk.co.uk/t5/Email/TalkTalk-and-DKIM/m-p/3095081#M185235 <P>I look after our church emails and we have a selection of email forwarding addresses.</P><P>This has worked well for many years but in the last couple of months all the incoming mails from users with a&nbsp;<a href="https://community.talktalk.co.uk/t5/user/viewprofilepage/user-id/54292">@talktalk</a>.net address have been bounced back with DKIM/DMARK errors. All other users are working normally.</P><P>I have been in contact with our provider Fastmail and they say that I need to get all my TalkTalk users to DKIM sign their mails. This obviously is not easy as I have no control on who sends us messages but I do have some regular TalkTalk users.</P><P>I would love to get this resolved so can you help please. I can send more details if requested.</P><P>Thank you&nbsp;</P><P>David B</P> Fri, 31 Jan 2025 12:18:06 GMT https://community.talktalk.co.uk/t5/Email/TalkTalk-and-DKIM/m-p/3095081#M185235 D-ForestFold 2025-01-31T12:18:06Z https://community.talktalk.co.uk/t5/Email/TalkTalk-and-DKIM/m-p/3095128#M185244 <P>Hi David B, our email team advise me that forwarding mail through our servers will no longer work.
