wiki: mail() function error
I don't see email notifications coming from the wiki.
And checking that, I got this error when attemptling to manually request a new confirmation email:
Alpine Linux could not send your confirmation mail. Please check your email address for invalid characters. Mailer returned: Unknown error in PHP's mail() function.
The saved address does look ok to me,though. The only thing that could be special might be that I only added it after first signing up without an email address (optional field empty).
