[exim] retry rule lost_connection or tls_required

hi,

when trying to set a retry rule for lost_connection or tls_required as follows:
*               tls_required       F,2h,15m; F,1d,4h
*               lost_connection    F,2h,15m; F,1d,4h

you get the following errors when doing exim -bV
2006-10-15 21:38:53 Exim configuration error in line 489 of
/usr/local/etc/exim/configure:
unknown or malformed retry error "lost_connection"
2006-10-15 21:38:00 Exim configuration error in line 488 of
/usr/local/etc/exim/configure:
unknown or malformed retry error "tls_required"

by removing the retry parameters from each rule exim -bV runs fine.
*               tls_required
*               lost_connection

us this suppose to be like this, using wrong format or is this a bug?

Exim version 4.62 #0 (FreeBSD 6.1) built 22-Sep-2006 18:21:07

thanks for all help in advance.
