Updating from 1.5 to 1.6 broke rerouting for webforms

Thanks for the report. Sorry I believe it was caused by 📌 Change to the phases Active .

I took the code that alters "to" out of LegacyMailerHelper::emailFromArray() because this was too late and was causing wrong languages. It's tricky because whatever order I do things in seems to break some specific case😃.

Potentially we can fix something like this:

• Remove the new @trigger_error in BaseEmailTrait::setAddress.
• Put back the code removed from LegacyMailerHelper. NB if code alters the to address in hook_mail_alter (during the build phase) they should note that it won't affect the language (which is based on checking if the "to" address belongs to a user, and using that user's language) as it's too late.
• Keep the new code in LegacyEmailBuilder to set "to" during the init phase - this is a better time to set "to" in general because it can affect language.

I added a warning to the release note.

Fixed in v2 next backport to v1

v1 MR is ready for review and test please

I tested the 1.6 + patch file based on "24ec304e - V1 backport".
This work as expected for us. Both in webform mails, and other mails.

Great thanks

I created a 1.6.1 release containing this fix.

Thanks for the quick response and the new release!
