[Mailman-Users] messages not archiving

[List Manager]

Hello,

I've recently upgraded my list hosting server by essentially doing a fresh 
install on a new server and then recreating the lists and transferring over 
their archives over. I ran bin/arch and pickled the mailboxes. Everything 
is working fine, except the messages are not posting to the archives. What 
did I miss?

I'm desperate to get this fixed. Any ideas would be welcome.

Best wishes,
Rae
