Problem:
gMail rejects emails missing a "MessageID" header, and email originating from my Samsung phone does not include the MessageID header.

What I see: Email originating from my phone's email app [Samsung email Version 6.1.72.1] does not include a message header (when using my private domain's SMTP server, parked at GoDaddy/SecureServer.Net). Therefore, eMail from me/myphone on that account, to any gMail user, is rejected by the Google servers with a 500/550 error, and bounced.

On my phone, other email with another domain includes a MessageID header. I had assumed that a SMTP server creates that globally unique ID; but since the MessageID does show up on those emails, I'm not sure.

Other Info:

  1. eMails from my thunderbird client, sending through the same domain/SMTP, do include the MessageID
  2. emails from my phone client, through another, second domain, do include the messageID
  3. emails from the WebClient for SecureServer.Net do include the MessageID
  4. deleting my domain email from the phone app, and recreating it, does not change anything
  5. GoDaddy/ReSeller phone-help was not helpful. That first-layer help asserts that an escalation reported to him that: there is no SMTP server setting which can explain what's going on, and; the expectation is that their SMTP server creates all MessageID headers and puts them in all emails.
  6. I am looking at the as-sent, raw emails by sending emails to my domain which I pick up on my Thunderbird.
  7. I posted this issue on the Samsung help, and no one has answered. An earlier, similar question had a single answer, which was to ask Google at the google account help page. Not helpful, for me.

So, Questions:

  • Which application client or server is generating the MessageID line, and does email in "sent mail" include a MessageID because the client retrieves the MessageID from the SMTP server as part of the send process?

  • how do I force eMail, from my domain on my Samsung phone's email app, to include a MessageID ...

... so I can use my phone to write letters to gMail users

I had the same error, and was trying to get the messageId into my e-mails.

But the problem was not a wrong client or SMTP server, it was a missing "SPF record" in the DNS records of my domain. Google changed policies for incoming e-mails, which now require an SPF record.

If you have access to the DNS records of the domain, try to add a TXT field with SPF information.

There are some details regarding SPF:

I recently had this issue when using the Samsung Mail app. I switched to the MS Outlook App and the issue no longer occurs.

I did not make any changes to SPF records, they were already in place and functional for years.
