I’ve just migrated a large number of posts from MyBB and there were many jobs scheduled. I was using Gmail’s SMTP to send emails (our forum is low volume). The migration seems to have triggered digest email jobs ({"type"=>"digest", "user_id"=>4889, "current_site_id"=>"default"}), and this triggered Gmail’s STMP rate limiting:
Job exception: Wrapped Net::SMTPAuthenticationError: 454 4.7.0 Too many login attempts, please try again later. ow2sm11059574pdb.14 - gsmtp
Would it be possible to not trigger the digest after migration, since it doesn’t exactly make sense to email users of all the “new” posts?
I don’t recall having this problem for other migrations we’ve done for customers, so I am not convinced this is a “bug”. But we’ll take a look, I guess.
Digests have been actually triggered. I’m receiving autoresponders from people on vacation etc. Glad I was using Gmail and didn’t spam absolutely everyone.
I’ve just checked disable digest emails but that should be a big warning before migration. Maybe add it as a comment in the migration script?
The digest mails aren’t sent during the import, they are sent after the import.
During the import all emails are disabled, but as soon as the import is finished and Discourse is started, it sees a bunch of users that haven’t visited the forum for a certain amount of time and begins to send digest emails.
A quick solution would be to not automatically enable emails after the import (still it would send the digest mails as soon as emails would be enabled). A better solution would be some sort of grace period after an import where no digest emails should be sent, but I guess that’s not possible at the moment.
I don’t run imports on production servers with sidekiq running, emails being sent, etc. You definitely want to see what the imported data looks like before going into production with it. Every import is a special snowflake with its own surprises and requirements.
If you are running an import onto a live production site, disable emails in settings, or add this to the initialize method of your script:
