LegacyEmailBuilder doesn't allow changes in the legacy_message, made during an hook_mail_alter().

jeroent → closed merge request !121

Patch doesn't seem to work against 2.x

AFAICS that patch will make the parameters available contained in the legacy_message param - which works I guess, but isn't what I'd recommend. In my view the legacy_message param is an implementation detail of LegacyMailer and isn't part of the interface. Instead all the information from $message should be available via $email.

The legacy parameters should be available directly via getParams(), but they are missing. We can do that in LegacyMailerHelper::emailFromArray() something like this

// Parameters.
$email->setParams($message['params'])

adamps → changed the visibility of the branch 3487274-1.5 to hidden.

I fixed it in 🐛 Updating from 1.5 to 1.6 broke rerouting for webforms Needs work which was changing the same function anyway
