Just after installing v6.6.1 the set up routine went through a series of configurations. One of them was the initial set up of the mail configuration. The initial test email was successful and was received. However, when I went back to test it again manually in Configuration > Mail Settings the test claimed to "Message Test e-mail from https://xxxxxxxx.org/ successfully sent to . . ." however, I didn't receive the test email. I am using Joomla! 3.9.14. Here are my AcyMailing settings:
Using your server
PHP Mail Function
Encoding format: 8 bit
Accept special chars in email addresses
DKIM is set to off
Any suggestions on how to fix this?
One other question, how do I change the email address the test is sent to?
