The mailing list for listmasters using Sympa

["Steve Sobol - NTF" <address@concealed>]

Hello,

I'm moving some mailing lists from mlmmj to Sympa. I have a directory
containing a list of archived messages and a script that parses the posting
dates and sorts them into directories. (the paths look like YYYY/MM/<message
number>)

I've created an empty list in Sympa. What I need to know is how I can get
Sympa to recognize that those old messages exist so that list members can
log into the web UI and read the archives.

Thanks
--Steve
