[Mailman-Users] Could I synchronise while it's sending?

[Michel Remacle]

Hello,

(I'm new to this and I speak french so...)

I would like to know if it's possible to:

1- add 70.000 people to a list (ok)
2- send a message to all of them (ok, takes about 8 hours on my server)
3- synchronise before the 8 hours have passed ??

E.G.: Knowing that it takes +/- 8 hours to send the 70.000 messages, can I
synchronise my list before the end of the 8 hours?

Thanks for reading,
Michel
