[Exim] Retry rules

I have inbound servers which take mail & re-deliver to mail holding servers.
I always want an inbound server to attempt delivery to a holding server,
even if that server has not accepted mail moments earlier.

Will a retry rule such as this enable this behaviour:

[10.15.20.41]        *           F,5m,1s; G,4d,1h,1.5

Cheers

John
