FORM not sending eMail using MS IIS 2019

[paul.maechler]

I did spend more than 2h creating a form to send a mail.
Tried really everything. Connection to SMTP host (same subnet as webserver) work somehow. But the script is not sending any data to the SMTP server.

Also tried using formdata.csv. This is ending with "cannot create file". Bit the creation process via FTP worked perfect.

Server is Win2019, PHP 8.1.

Ist there a chance to make that work or should I give up and use something else ?

Thanks for any assistance.

Thanks. Yes it would be helpful if the error log was enabled. Have you configured SMTP to run in Windows server 2019?
