Issues relating to the email-related features, such as "enotif" watchlist notifications, Special:ConfirmEmail, Special:EmailUser, etc.
This project is part of the core MediaWiki software itself.
For issues pertaining to Wikimedia's email/SMTP infrastructure see Mail instead.
This tag is distinct from MediaWiki-Core-Notifications, which covers issues in the new notifications system being developed in 2025.
On April 29th, I also encountered the same "Sendmail exited with non-zero exit code 74" on the Estonian Wikipedia. The user to whom I sent the mail mentioned today that he got the letter, but not the notification on Wikipedia.

This is still happening, ~3.3k per in last 4 weeks:
Hi all, I just experienced this error as well as a few community members have reached out that they did not receive an email from me during the Community Insights distribution yesterday (however, they did receive an echo ping to check their email). When I tried to send a message directly via EmailUser on the project to one of those community members just now to troubleshoot, I got the Sendmail exited with non-zero exit code 74 message. I'm unsure of the scale of the unsent emails as I didn't get a failure for these with the EmailUser API script I was using, but it should be visible in yesterday's log (if such a log exists, I presume it does per @Krinkle's last message but I seem to not have access).

While I understand the confusion I believe this was a deliberate design decision. The problem is that the email is generated once, but the link is possibly clicked much, much later. The user can change their preferences any time. Who knows if they accept emails right now? The receiver of the email can only learn this when they visit the email page.
Change #678382 abandoned by Thiemo Kreuz (WMDE):
[mediawiki/core@master] mail: Remove user email link if email is disabled
Reason:
5 years old. The code also moved to a very different place. Can still be found via the ticket if needed.
Marking this Epic as resolved! 🎉 All subtasks are resolved, declined, or in final QA.
