This is the error:
2023-01-20 08:26:22 SERVER -> CLIENT: 535 Incorrect authentication data
2023-01-20 08:26:22 SMTP ERROR: Username command failed: 535 Incorrect authentication data
SMTP Error: Could not authenticate
I've never heard of using SMTP without a username and password. The error implies it is expecting one even though your instructions say not to use one.
Can I get FTP access? It might be trying to authenticate with a blank value and I may need to update the code to skip authentication when the username and password are left blank.
Did this help? Tips are appreciated...
