[exim] send old mail queue

Hi

I've restart my mail relay for an hw maintenance.
Now in the /var/spool/exim4/input I've found about 340 old mails.
This mail there aren't in the queue, I've check it by mailq command.
I've not found any entry for the messages id found in
/var/spool/exim4/input
There is a way to spool this old mails?
Exim try it later?
