I have already used this config to log in:
URL: smtp.zoho.eu
Port: 587
Encryption: TLS
Mail: info@freilich.me
Pass: [#ApplicationPassword#]
URL: smtp.zoho.eu
Port: 465
Encryption: SSL

..........
URL: smtppro.zoho.eu
Port: 587
Encryption: TLS
Mail: info@freilich.me
Pass: [#ApplicationPassword#]
URL: smtppro.zoho.eu
Port: 465
Encryption: SSL
Mail: info@freilich.me
Pass: [#ApplicationPassword#]
Nothing did work. I can not send any Mail with Zoho. Apparently the Log gives nothing back then a 500 Error on Zoho side.
