[olug] Bad Practice (Pet Peeve O' Mine)

[mØntar3]

    Changing a thread topic without generating a new email 
discombobulates thread indexes and makes a sender look lazy. Hence, the 
question, "Why should I answer a lazy person?"

    An email message has a thing called a "Message-ID" in its header. 
When an agent generates a reply to an email, the agent marks the reply 
with a header name "In-Reply-To." The "In-Reply-To" name references the 
previous email's "Message-ID" value.

    Changing an email subject (and blanking out the message body) 
without composing a separate email, causes the new thread topic to be 
sorted into the previous topic's thread index.  :-P
