I am having the same issue, but intermittently.

Well, finally I have stopped email routing and then use a paid service to instead.

Can you give a bit more detailed what exactly you observed and how the fixes are looking like? That would give as a bit more trust.

I meet the same problem. Please fix it as soon as possible

This problem still persists. I designated cPanel instead of CF to forward my emails. If Google rejects it, the email can be viewed in cPanel. This is not the best option, but at least I can see my incoming emails.

Je rencontre exactement le même problème, c’est très embêtant !

I am also having this issue. I have the following SPF record.
v=spf1 include:_spf.mx.cloudflare.net ~all
And
_dmarc v=DMARC1; p=none; rua=…
It seems to happen if the original sender doesn’t have an active DMARC (though this may be coincidental).

Same problem here… loads of emails not getting forwarded:

The incident report claims that it a fix was implemented many days ago, and it is now “resolved”, but I had another email with the same problem only 10 mins ago.

EDIT and another couple of emails not forwarded 2 mins ago… please please fix this… and please update your incident page to show that it is not resolved.

Adding a +1 here, and it’s Google’s OWN email.

With the deprecation of Google Domains, I need to move over email forward/routing. This is a big deal, and a big blocker for me.

gave up gmail, using another provider. Good to go for now.

I hear what you’re saying, and I get it. This is going to be a problem with any and all third-party email routing/forwarding systems because the nature of spammers.

With that said, moving to another mailbox provider is easier said than done: I’ve used MS365, Zoho, and iCloud – three alternatives I know of to Google’s Suite, and I don’t like any of their web interfaces. On top of that this is a 20 year old account and Google has vast third-party integration and support.

It seems like the “only” solution would be to pay for Google Workspace and use their own MX routing. :face_with_diagonal_mouth:

Gmail has an imap importer too I guess.
