It depends. There are options to tell logrotate to use, or not use,
dates in the new filename, and what compression to use or not use. So
the names can vary.

By far the easiest solution is to put your "| mail" into prerotate
section. That way you know exactly what the name is. Or maybe not due to
that * in the name glob...

Perhaps look into renamecopy described in man logrotate
