I have setup a Joomla website with registration confirmation through admin.
- Global setting for mail sending - set to yes
- The user is set to get system mails
- Info mail to admin on registration - set to yes
It worked properly for weeks. I didn't change the settings. I have done only updates. I noticed now because people asked me, why they are not yet confirmed.
I did some tests:
- the registrant gets the first mail
- eventBooking does send mails
- the testmail worked
I don't have any idea what I could check additionally.
Installed extensions:
- EventBooking
- AdminTools
- JEvents
- Kunena
- AcyMailing 6
All mail sending happens via PHP/sendmail.
