#373826 - 26/04/2022 10:15 Migrated from Google Workspace

I have a domain that is used for family emails, 4 email addresses. Google decided they were going to strt charging so I decided to move to MS365. I've migrated everything but there's still some emails appearing in the google mailboxes, not very many and mostly from a couple of senders.

Clearly mx records must be setup correctly because 99.9% of emails are being routed correctly, I'm at a loss as to why this is happening.

Has anybody had similar issues?

How long since you made the changeover? Perhaps the other senders' servers aren't updating as fast as most.

Are the senders that still show up in the google mails also using google mail?

You might want to use DigWebInterface to check your MX records. Type in your domain, pick type MX and select ALL in the name servers. This will show the MX results from several different public DNS servers like Google and Cloudflare.

You should also do the Authoritative nameserver option as that will show if the DNS servers hosting your domain are providing the correct information.


After looking at your email attachment, I don't see any issues with your DNS. I think something is wrong with the DNS on the senders side.

Everything looks like it's pointing to hotmail, and GoDaddy default nameservers

Yeah, but how??? And how can it be fixed? I can't imagine how they could be pointing at the wrong MX port. Most of the stuff is random mail list stuff, but there are a couple that I'd really like to route correctly.

The email you posted appears to be from the hl.co.uk domain.

So I looked up _that_ domain, and tested their DNS servers: all out of commission, it seems: they don't find any domains I throw at them. So the sender is perhaps falling back on a very old cached copy of your DNS record.

Others agree with that?

I was wondering if there might be a TTL issue. Yours sounds more likely.

I did look at the TTL, and the maximum interval there was about 8 days.. so long since expired.

No.

They aren't out of commission, they are just setup as authoritative DNS servers for the domains they serve and aren't answering queries for other domains. Which is perfectly normal for Internet facing DNS servers that aren't providing general DNS services to the public.

Code:
[email protected] ~> dig hl.co.uk @hldns03.hargreaveslansdown.co.uk

; <<>> DiG 9.10.6 <<>> hl.co.uk @hldns03.hargreaveslansdown.co.uk

Also, it is unlikely that hl.co.uk (a bit investment management company, coincidentally the one that I manage my pension via) are using those same DNS servers for the hosts that are sending their outgoing email.

Also, it won't be hl.co.uk that is actually sending the email.

The message headers show that it is actually adobe.net infrastructure that is sending the email. So the mail will be coming from their Marketo email marketing automation system. The only way hl.co.uk will be involved is with setting up DNS records correctly to allow adobe.net/Marketo to deliver mail on their behalf.

For my sins, I've worked on projects using both Marketo and their competition Marketing Cloud to deliver both transactional and marketing email frown

So, wouldn't Marketo just use whatever comes back through the DNS records? Surely they must check and refresh these regularly?

They should do, yes.

The fact that this is happening with multiple senders would suggest there is a general problem somewhere. Unless they are all from Marketo ?

There is certainly nothing obviously wrongly set up from looking at your DNS records.

Can you share the headers of those ? (we don't need the body of the message)

They are both from Marketo. Clearly Marketo have an issue with caching the old MX records for your domain.

Good luck on finding someone to fix that &#128528;

Though I expect at some point it will just magically get fixed.

Good information. I posted that link to Twitter because I have some twitter friends who might be affected, including my housemates.
