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:

```auto
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:

```auto

```

SMTP host: my iredmail hostname  
SMTP encryption type: TLS  
Port: 25  
SMTP authentication mode: Plain with my username and password
