SMTP/POP3 Logging

I am using Aspose.Email  and calling SMTP/POP3 Methods to Send/Receive emails.
I could see that SMTP, POP3 level logging is possible with Pop3DiagnosticLog/SmtpDiagnosticLog config file settings. I am calling .NET methods from VB using COM Interop and also <applicationname>.config is not an option. Please would you let me know if I could create SMTP, POP3 Logs without using a config file.
