The mailing list for listmasters using Sympa

[Ahmad Gharbeia <address@concealed>]

Hallo,

I eventually managed to install and configure Sympa on my server. It
wasn't easy. The documentation on sympa.org tackles concepts with little
practical detail and assumes good knowledge of many other components.

The reason I'm choosing Sympa is the need for the sub-lists feature. But
I don't know how to use it!

I read https://www.sympa.org/faq/sub-list but I cannot find anything
under datasources configuration to enable a list to be a sub list of
another. Any hints?

Regards,
Ahmad
