Clear the SMTP Session Log

Demonstrates the Chilkat MailMan.ClearSmtpSessionLog method, which clears the current contents of the SmtpSessionLog property. This example opens an SMTP connection (which populates the log) and then clears it.

Background: Like its POP3 counterpart, the SmtpSessionLog records the raw client/server dialog — the EHLO, AUTH, MAIL FROM, RCPT TO, and DATA exchanges — which is the first thing to inspect when a send fails. Clearing it between sends keeps the captured log focused on the operation you care about rather than the entire history of a reused MailMan object.
