| I have discovered another undocumented feature. It turned out that one can use `$DEFAULT_zzz` placeholders in pipelines, too. Also I found out that one has to explicitly pass `subject: "$DEFAULT_SUBJECT" and to: "$DEFAULT_TO"`, although it would be nice if the plugin used these values by default. Having discovered all that, we can now use email-ext in our project, despite its poor documentation. The question about `ListRecipientProvider` remains open, though. |
