Then there must be something wrong with my configuration.
http://n3.nabble.com/Culture-Forum-Discussion-f37461.html1) Posting in the forum correctly displays the message in the forum and sends it to the mailing list, which delivers it to all subscribers.
2) Using the posting-by-email feature (i.e. ml-node+37461-anumber@n3.nabble.com) works as well as the previous one.
3) Sending a mail to the mailing list works, but the message doesn't appear in the forum.
3) Logging in using the mailing list interface (Sympa) with the Nabble account (lists+anumber-37461@n3.nabble.com) and password and posting a message successfully delivers the message to the suscribers, but the message doesn't appear in the forum.
I've checked the "suscriber options" in Sympa for the Nabble suscriber and "standard (direct reception)" is selected.
Any clues about what else to check? Thanks in advance.
