Error when using PowerBuilder 2022 R2 Beta's SMTP functionality

Hi,

I have the following codes that I based from the sample given in Appeon side. I'm using PowerBuilder 2022 R2 Beta. My IT department said that we can send email through our SMTP server without authentication, and leave Password, SecureProtocol, EnableTLS blank. When I try to send using send(), I get return code of -4 or -15.

1. Are Password, secureProtocol, EnableTLS required even when our SMTP server doesn't require authentication? If so, what values should I use for SMTP that doesn't require authentication?

2. Is there a list of error code and how to solve it where I can refer to to resolve issues that I encounter?

Thank you.

Yuko

// Send it

//li_rc = lsc_mail.SendAsync() // Send email asynchronously using this function

messagebox('li_rc', li_rc)

// Reset and Destroy
lsc_mail.Message.Reset()
Destroy lsc_mail
