The SMTP Commands to send an e-mail

[TurrieLex]

Which SMTP commands are communicated with the SMTP server to send an e-mail message? Can I see a log of all operations?

Yes, you can see all commands using a trace file. By default, tracing is NOT switched on. Tracing is enabled/disabled per channel.
You can enable tracing for SMTP by specifying a log file for the particular channel in the registry:
HKLM\Software\ActiveXperts\SMS Messaging Server\Trace\SMTP.xxxx ,
where xxxx is the actual channel number.
After you change this registry value, you MUST restart the SMS Messaging Server engine (service) for the changes to take effect.
