That's unduly complex and disruptive. Don't do any of that.

Note: the following is for standard Mailman. Plesk may be different.

First make sure you have

add_virtualhost('their.web.domain', 'their.email.domain')

im mm_cfg.py.

Then for each affected list you run Mailman's

bin/withlist -l -r fix_url listname --urlhost=their.web.domain

That takes care of most of it, but there may be issues with delivery of
mail to Mailman. If you use Postfix with Postfix-Mailman integration for
automatic generation of aliases and virtual mappings, you probably also
want to add 'their.email.domain' to the POSTFIX_STYLE_VIRTUAL_DOMAINS
list in mm_cfg.py. Then running Mailman's


is all you need. In other cases, you may need to manually update virtual
mappings. Aliases generally don't need to be changed.
