I have a user trying to change their email address on the account, and they never see a verification email. I have no issues with general emails being sent and have regular inflow of users signing up, so email is clearly working, but not for this one case.
If I try to add a new email, I get this screen:
And I can see the pending one on my profile:
However, no email is recorded in the email logs, and no information is logged in the Discourse logs. I checked the email provider as well and no emails appear to hit that either. If I repeat adding the same email, I get multiple entries but never any emails sent.
If I do the same on this forum (the meta-one) it works as expected and I see get the email.
So apparently some setting is incorrect in my instance. Any clues as to why this would happen?
