Hi,
This may be out of scope a bit but thought I would give it a try.
We have setup iRedmail and are trying to connect up to it from our Mautic instance. Connection Test is working fine, however when trying to send a test email getting the following error:
Expected response code 354 but got code "554", with message "554 5.5.1 Error: no valid recipients "
I know this is a redmail config issue, but maybe someone here can shed some light on the matter.
The error on redmail side is the following:
