Absolutely. mail.python.org for example currently has 261 Mailman 2.1 lists and 134 Mailman 3 lists. The only consideration is that during migration of a list from Mailman 2.1 to Mailman 3 there may be a period of time during which both a Mailman 2.1 and a Mailman 3 list exist with the same name, and you have to think about which list should get incoming mail and how to configure the MTA to do that. On mail.python.org with Postfix we use the alias_domain feature of Mailman 3 <https://docs.mailman3.org/projects/mailman/en/latest/src/mailman/docs/mta.html#unusual-postfix-configuration> so that delivery to Mailman 3 begins with a virtual alias mapping and Mailman 2.1 also uses a virtual alias mapping. Then if there are both MM 2.1 and MM3 lists with the same name, the order of the ``` hash:/srv/mailman/data/virtual-mailman # MM 2.1 hash:/opt/mailman/mm/var/data/postfix_vmap # MM 3 ``` lines in `virtual_alias_maps` determines which list gets the mail. -- Mark Sapiro <m...@msapiro.net> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B.
