Sorry in advance if this is an obvious question, but I'm not finding it in the documentation.
I've been testing the mailing list subscription function, and see that the default confirmation says "To confirm this subscription, reply to this email or click here." Clicking the link works to confirm subscription, but replying to the confirmation (the reply-to address formatted like civicrmc.NN.NN.NNN@mydomain.org) doesn't work.
Where are these messages supposed to be handled? It doesn't seem to be bounce or email-to-activity processing (https://docs.civicrm.org/sysadmin/en/latest/setup/civimail/#configuring-inbound-email-processing). My bounce processing is set up and working.
Is the message template incorrect? Or am I missing a configuration somewhere?
Thanks!
