The mailing list for listmasters using Sympa

[vicka <address@concealed>]

Hi sympa-users,

I installed sympa over postfix (3.4.14-0+deb10u1 armhf)
on Raspbian GNU/Linux 10 (buster).

At first it ... worked a little. I could use wws and create a list and
the welcome message was sent.

But sending mail to it was returned user unknown.

I tried following the directions here:

https://tribut.de/blog/sympa-and-postfix

and also uninstalling/reinstalling.

I can still see wws but now making lists doesn't even send a welcome
message.

Please, any help much appreciated!

Thank you,
