Should Mailman personalize each non-digest delivery? This is often useful for announce-only lists, but read the details section for a discussion of important performance issues. personalize (nondigest): Should Mailman personalize each non-digest delivery? This is often useful for announce-only lists, but read the details section for a discussion of important performance issues.

Normally, Mailman sends the regular delivery messages to the mail server in batches. This is much more efficent because it reduces the amount of traffic between Mailman and the mail server.

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.

Select No to disable personalization and send messages to the members in batches. Select Yes to personalize deliveries and allow additional substitution variables in message headers and footers (see below). In addition, by selecting Full Personalization, the To header of posted messages will be modified to include the member's address instead of the list's posting address.

When personalization is enabled, a few more expansion variables that can be included in the message header and message footer.

These additional substitution variables will be available for your headers and footers, when this feature is enabled:

  • user_address - The address of the user, coerced to lower case.
  • user_delivered_to - The case-preserved address that the user is subscribed with.
  • user_password - The user's password.
  • user_name - The user's full name.
  • user_optionsurl - The url to the user's option page.
