The mailing list for listmasters using Sympa

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

Hello,

I'm moving mailing lists from a couple other mailing list managers to our
Sympa server.

Some of them are on SourceForge, which allows you to export mail archives in
mbox format.

A handful are hosted on a server running mlmmj, with archives generated by
MHonArc.

Is there a relatively easy way to import those archives into Sympa?

Also, management wants me to create the new lists now. Can I create those
lists, then import the archives later, without breaking anything?

Thanks
--Steve
