That header is used to tell the recipient's email software what
message-ID the reply is to, so that the response can be threaded.
If you delete the message-ID, a new one is added by the next server
that handles the message.
If you are going to delete this, why supply it in the first place?
This is used along with the IN-REPLY-TO header for threading. It may
contain more Message-IDs from the thread. Useful on a mailing list in
case someone following the thread has blocked some contributors or
deleted/not received the message to which you just replied.
Given that you set this on a per-message basis as High/Normal/Low,
it's not a security/privacy issue at all. Deleting it just means all
your messages default to Normal priority.

Having it in those headers in the messages you post means you are
replying to a thread containing the content, not that you posted the
Besides, unless the user has specifically set their mailer to do
something different, the bit after the "@" often defaults to the
domain in their email address.

Only if for each thread you use a unique subject line that will never
be repeated, and you can guarantee that everybody reading the threads
only ever receives email from people who do the same.
