the mail server in batches. This is much more efficent
because it reduces the amount of traffic between Mailman and
the mail server.
<p>However, some lists can benefit from a more personalized
approach. In this case, Mailman crafts a new message for
each member on the regular delivery list. Turning this
feature on may degrade the performance of your site, so you
need to carefully consider whether the trade-off is worth it,
or whether there are other ways to accomplish what you want.
You should also carefully monitor your system load to make
sure it is acceptable.
<p>Select <em>No</em> to disable personalization and send
messages to the members in batches. Select <em>Yes</em> to
personalize deliveries and allow additional substitution
variables in message headers and footers (see below). In
addition, by selecting <em>Full Personalization</em>, the
<code>To</code> header of posted messages will be modified to
include the member's address instead of the list's posting
address.
<p>When personalization is enabled, a few more expansion
variables that can be included in the <a
href="?VARHELP=nondigest/msg_header">message header</a> and
<a href="?VARHELP=nondigest/msg_footer">message footer</a>.
<p>These additional substitution variables will be available
for your headers and footers, when this feature is enabled:
<ul><li><b>user_address</b> - The address of the user,
coerced to lower case.
<li><b>user_delivered_to</b> - The case-preserved address
that the user is subscribed with.

<li><b>user_optionsurl</b> - The url to the user's option
