Interesting. We moved our Mailman instance from CentOS 5.x running
Mailman 2.1.9 to SLES version ? running Mailman 2.1.18-1 and python 2.7.
When we switched, the OS was some concern but the main decision we made
was to use Mailman from the source at list.org and python 2.7. We have
made some custom modifications here and getting Mailman from the source
would allow us to upgrade Mailman a little easier than from the OS
maintainer. By divorcing our Mailman instance from the version
provided by the OS maintainer, we can pick up our instance and switch to
a newer host easier.
