== 4.69. Why aren't my mm_cfg.py settings for DEFAULT_URL_PATTERN, DEFAULT_URL_HOST and DEFAULT_EMAIL_HOST effective? ==

This is covered in other FAQs, but it comes up often enough that it deserves a FAQ of its own.

Many things in Mailman are based on the value of a hidden list attribute web_page_url. These include URLs on the admin pages, URLs in archives, URLs in RFC2369 headers, etc., and when VIRTUAL_HOST_OVERVIEW has not been set Off, what lists appear on what 'overview' pages.

The web_page_url attribute is set at list creation time from DEFAULT_URL_PATTERN and DEFAULT_URL_HOST or in the case of virtual hosts, from the current or specified web host. Subsequent changes to DEFAULT_URL_PATTERN and DEFAULT_URL_HOST do not affect existing lists.

The same is true of the list's host_name attribute which is set at list creation time from DEFAULT_EMAIL_HOST or the current or specified email host, although the list's host_name is visible and settable on the web admin General Options page.

In order to change existing lists, you run fix_url. Run

{{{
 bin/fix_url.py
}}}

stand alone for it's help information, but briefly, to run fix_url on a single list, run

{{{
 bin/withlist -l -r fix_url <listname> [fix_url options]
}}}

To run it on all lists at once, run

{{{
 bin/withlist -l -a -r fix_url -- [fix_url options]
}}}

The '--' is only required if you specify fix_url options. It separates the fix_url options from the withlist options and isn't required in the first case as the list name does this in that case.
{{{#!wiki note
If you have lists in multiple virtual domains, you need to run fix_url one list at a time with the appropriate --urlhost option
}}}
