To clarify, here is the quote from the usage:
    -s <share>    Share name (or - for all) from which path is offset
                  (don't include the 'f' mangle)
                  NOTE: if unmangle option (-m) is not set then the share name
                  is optional and if not specified then it must instead be
                  included in mangled form as part of the file/directory names.

So, you can do any of the following assuming your share name is '/'

With mangling
BackupPC_deleteFile.pl -h hostname -n - -d 4 f%2f/fvar/flog/fmaillog
BackupPC_deleteFile.pl -h hostname -n - -s / -d 4 /fvar/flog/fmaillog
BackupPC_deleteFile.pl -h hostname -n - -s %2f -d 4 /fvar/flog/fmaillog

Without mangling:
BackupPC_deleteFile.pl -h hostname -n - -s / -m -d 4 /var/log/maillog
BackupPC_deleteFile.pl -h hostname -n - -s %2f -m -d 4 /var/log/maillog

You could also use '-s -' to include any share and you could remove
the leading slash before (f)var in all but the first example.
