A bug in Discourse is causing email replies to bounce with the message “Email issue – Reply User Not Matching”. The issue is due to a bug introduced in commit 1bb485f and fixed in d51019e, which caused emails sent between these two commits to not have the user associated with the email log.
This resulted in emails using a reply_key being rejected. A migration has been pushed to fix the affected email_logs, and upgrading to the latest version is recommended. The issue is also linked to repeated digest emails being sent to users, which can be stopped by turning off all emails. tobiaseigen and ffub have reported the issue, while zogstrip helped debug the problem and provided a solution.
We’re getting reports of email replies to discourse bouncing with “Email issue – Reply User Not Matching” in the subject. Is this a bug or are we doing something wrong?
I got a report earlier this week and again from another member yesterday. This morning I updated to latest and tested myself, and have not seen the problem. Of course, breaking troubleshooting rule number one and not attempting to replicate it first.
I’ve asked those two members to let me know if it occurs again.
That is interesting. Which version are you running exactly?
I don not use pop3 to get mails into discourse, but post them using curl and if the user mail address is wrong, I only get back a HTTP 500 error with no reason at all. The reason is however logged in Discourse.
if this problem is not related, let me know and I will file a separate bug report.
@tobiaseigen helped me debug this issue. It’s due to the bug introduced in 1bb485f and fixed in d51019e.
All emails sent between these two commits (only a couple of days) will not have the user associated to the email log. Which means that whenever we process an incoming email that uses a reply_key, it won’t match any user and will thus be rejected.
I just pushed a migration that should fix all the email_logs that were created between that period and I highly recommend that you guys upgrade to latest ASAP if you haven’t already.
Mine sent 4x digests to some users today lots of emails.
Also started seeing reply user not matching.
I saw the no user in the email sent list and guessed thats why digests were repeating.
Forgot to mention this: It was resending the digest emails to the same people repeatedly every couple of hours I turned off digest emails but it seemed to keep sending. Only when I turned off all emails did it stop.
lots of emails.
