I'm new to MM3. I just finished install it. I setup a test list with default settings as test1@domain. I added a user to the list via Mass Subscription with Pre confirm check and Pre approved check. Inside the user inbox in GMail account received email from address test1-confirm@domain ( I added this erp_confirm_format: $address to [mta] in /etc/mailman3/mailman.cfg) with Your confirmation is needed to join the test1@domain mailing list. I replied to the email and I received another email as test1-bounce@domain. I went to my mailing test1@domain. I found a user that I tried to add list in 'Subscription request' under 'Pending Confirmation'.
Could you help me to troubleshooting on this? Why I received a list-bounce@domain instead of successfully added or something.
Thanks, Marin
