gmail is modifying header(Message-ID) of incoming mails

Question

I sent a mail from my smtp server to gmail. The message-id that I got is: Message-ID: [email protected]> X-Google-Original-Message-ID:

Gmail appended extra parts in Message-id.

All I got on google that it can be an authentication issue.But source of mail shows: SPF:PASS

But DKIM is not present in the source. Do we require DKIM to be necessarily present in the mail's source?? What can I do to prevent header from being modified?

Answer 1

the msesage ID will be modified only if it does not obey RFC standard. so send mail with correct message id format

I got the same error and i really can't get my head around why google still adds it. My header looks like Message-ID: <[email protected]>, which to my understanding matches the requirements from the RFC. – Leptosome

Did anyone resolve this, I am still getting this and can't see anything wrong with my Message ID either. – Farwell

I solved the issue by surrounding the Message-ID with < and > brackets – Farwell

Answer 2

After many tries, I finally figured out that you need to add brackets enclosing the Message-Id

<[email protected]>
