Can not send email using Mox mailserver with SCRAM

[chiel1980]

Describe the bug
I can not seem to send email using Mox as mailserver. I tried SSMTP and SMTP with StartTLS but get an error in the debug logfile that there is an error with the SMTPclient

To Reproduce
Steps to reproduce the behavior:

1. Use starttls port 587 with MOX (certificate validation enabled or disabled does not matter)
2. Send a standard simple email
3. Error message being shown
4. See error

Expected behavior
An email to be send without an error :)

Please complete the following information:

• Browser: Brave 1.70.126
• IMAP daemon: Mox
• PHP version: 8.2
• SnappyMail Version: latest - debian apt version
• Mode: standalone
