The mailing list for listmasters using Sympa

[Tim Howe <address@concealed>]

I have just joined this list, and I have not yet set up Sympa.

However to your question about multiple domains: that appears to be a
base function of Sympa, and that is how I intend to use it (multiple
domains).

This is suggested in the docs here:
https://www.sympa.community/manual/install/generate-initial-configuration.html

When I get around to installing it on my server I may have more info.
Since mine is a new install I don't mind risking some breakage to find
the correct formula.  If you like, I will answer in more detail as I
figure it all out.

Since nobody else seems to be answering your question (at least not on the 
list).
