Password reset emails are not being sent by my OCS 18.104.22.168 instance. All other emails are being sent and received correctly, which makes me believe that my SMTP configuration is correct.
I’ve also set a bounce address, which is not getting any bounces after trying to reset a password (as described in Not receiving reset password email). I have also tested to recover passwords from users at gmail and riseup, to make sure the problem is not at incoming server. None of them are receiving the email, not even at spam box.
Debug features do not show any errors, and also there’s nothing shown at apache/php log.
I would appreciate any hints on how to further debug and solve this issue.
