Hi! My forum has a lot of imported users that have a specific email domain that doesn’t work anymore. A few thousand users have such an email address. It was not an issue until now, but I increased suppress digest email after days value, and my forum sent a lot of digest emails, including to a lo…

I think I might UserEmail.where("email like '%@brokendomain.com'").each do |e| e.update(email: SecureRandom.hex + "@email.invalid) end Yours could work too, but Im’ not sure if the User model got updated to be able to do a u.email.include? after they moved emails to another model/table.

For some reason I didn’t find this topic using the search… I guess I panicked! :sweat_smile: Thanks you very much for your fast answer!

But if there are a zillion email addresses like bademail.domain, maybe what you want to do is something like rake posts:remap['bademail.domain', 'no-email.invalid'] as described in Replace a string in all posts . That will make all of those email addresses such that Discourse won’t send to them. An…

Yeah, I thought about doing this to get rid of these email domains. I notice that a Discourse method creates @no-email.invalid emails: app/services/user_merger.rb main Invite .with_deleted .where(invited_by_id: @source_user.id) …

[afbeelding] Canapin: I’m not sure to understand why I should remap in posts I’m fairly certain that posts:remap remaps that domain across all tables, but they had to put it in some class. You could also just write your own replacement in the UserEmails table (or whatever it’s called). I’m …

Neat. So I guess this would do the trick? User.find_each do |u| if u.email.include? "@brokendomain.com" u.update(email: SecureRandom.hex + "@email.invalid") end end

I tried my script just to see if it was returning the target email addresses and it works. Your script should be faster than mine since you use a query to select specific email domains instead of looping through all the users. Thank you very much for your help :+1:

Ooops. Here’s the remap I meant. It’s just discourse remap old new See Change the domain name or rename your Discourse . I think that the above would work, but the UserEmails solution is probably a tiny bit better.

[afbeelding] pfaffman: I think that the above would work, but the UserEmails solution is probably a tiny bit better. Thank you. This is the one I used. More than 5000 users of a total of 17000 users had such email domains. No wonder the number of bounces when I increased suppress digest emai…

[afbeelding] pfaffman: I’m fairly certain that whatever.invalid will tell The World that it’s an invalid address and it won’t try to send it. This is special handling by Discourse for anything ending in .invalid, which is a reserved TLD.
