I'm having troubles with confirmation emails ( LimeSurvey Community Edition Version 5.1.5+210830):
i also have a lime survey 3 installation and it's working fine. With version 5 all emails are sent...but not the confirmation ones.
I have a user table with tokens (created from a csv import), confirmation email option flagged, but nothing...
I can log smtp and i don't have any request, so it's not a mail problem.

I also tried to workaround with the notices, using {TOKEN:EMAIL} in basic/advanced notice, but no luck...
If i use a static adress it sends the notice, with placeholder nothing happens.

Any idea of what i'm doing wrong? or can anyone confirm with latest limesurvey 5 the confirmation emails are working fine?

Thank you!

If it work in 3.X, if you are up to date in your LimeSUrvey 5.X version : you must report the issue.

Here : you can report 2 issues
- One for confirmation email
- One for admin notification email usage of {TOKEN:EMAIL} (if survey is not anonymous).

thank you, reported and fixed!
it was indeed a single bug for both problems ( github.com/LimeSurvey/LimeSurvey/commit/...f93d337f263cb68773eb )

Really excellent support.
